Hi everybody! Thanks so much for watching. Couple of *corrections* At one point in the video the word million sounds like the word billion. And the Canadian Shield got mixed up for the Rockies. Apologies!
History of the Earth My favorites would be all of it, and I'm in no hurry to get anywhere in particular. I guess I will be a little more excited when it reaches the Paleozoic Era. And I hope it takes a few episodes to get to the Permian Period, because this Old-life era is the least covered of all in other productions I've seen. I trust that I will like it all, as I am already. Thanks again.
Done ,I shared it . Thanks for your efforts and dedication to this project .
1:25 That is Peyto Lake in the Rocky Mountains of Alberta. Not in the Canadian Shield of the North West Territories.
I know, I’ve personally hiked up there to that exact spot and got pictures of my own.
This is how the Earth really formed. 4 billion years ago it looked like Saturn. ua-cam.com/video/CM0Hi0YwAJA/v-deo.html
Instead of dinosaurs and the other unpopular stuff, what about Snowball Earth, 700 My ago?
I for one remember those early days of earth with great fondness. It wasn't nearly as bad as the narrator makes it out to be. Sure, there were the occasional asteroid bombardment on the way to school, and the lack of breathable air or sustenance of any kind may not sound that cushy to you modern kids, but we didn't need luxuries like that. We had gneiss rocks to play with and a giant, nightmare inducing moon to look at at night. Those were simpler times..
Joe Biden, is that you? I thought you were running for the US Senate?

Love your wit!

A geologist uncovers a rock that's 69mil years old.
*"Gneiss."*
Geologists themselves may be "gneiss", steady, dependable - a "rock".
However, there is one catch....
They are notorious "fault-finders".
As well, they may take you for....
"Granite".
Lol.
:)
@@sentence2sentience835 theres a special time period in the earth's formation for people like you, and i think its pretty close to what's in this video... But i love bad puns so take the like and get in the time machine ;)
"Nice" wait what lol
You think you funny

This used to be confined to tv channels. Now they have nothing like it and here it is free to view on UA-cam. Great work.
Yeah. On Discovery Channel and National Geographic it's mostly about fishing, cars, drugs and other similar shows. There used to be such great shows that peaked my interest almost every day, now it's just once a month.
I haven’t watched tv in like 8 yrs lol
Tiger King 😴
now, its really rare to find this stuff on TV amid all the garbage
S pose you could make Gneis old gnome out of that.?
The narrator describes everything in such a profound way.
If you like it, His channel It's voices of the past, I recommend listening to the last Aztec themed video He has published It's a masterpiece
Julian Guastadisegno great surname!
It’s a pretty profound subject
Yeah, but a little much. The William Shatner of earth science, lol.
mjinba07 true, true, it can get a little overbearing. I think Carl Sagan in Cosmos had a good balance when it came to that.
Brilliant, love the narration - I'd never heard of the Moon being closer than it is now, tearing up the crust as it moved, terrifying.
Terrifying right!!
@Gluemonkey
RE: ". . . I'd never heard of the Moon being closer than it is now . . ."
You hadn't known that? I'm very much surprised, since that's been known for decades, just from the mathematics of the conservation of the angular momentum of two bodies orbiting a common barycenter (center of mass of a two-body system).
@@spaceman081447"just from the mathematics of the conservation of the angular momentum of two bodies orbiting a common barycenter (center of mass of a two-body system)." Duh.
Yes - "tear"ifying.
Ok I'll stop lol.
Yeah, not a connection everyone makes. A lot of us might have heard that the moon is getting further away, but that doesn't immediately lead us all to think that that probably goes backwards too, that it used to be closer.
Narrator: “this is gneiss”
Me: “nice.”
I think you're supposed to pronounce the 'g'.
We’d better get this out onto a tray.
I was taught it pronunciation as "niece" in my geology classes. I guess it probably depends where you come from
@@emceeboogieboots1608 nobody says niece LMAO..it's pronounced nice...always has been, your teacher must have been a moron
@@Circuit7Active Where are you from?
How do you pronounce Melbourne?
How do you pronounce Paris?
How do you pronounce aluminium?
Are you ALWAYS right?
I guess if you pronounce any of these wrong YOU are a moron😂
I am calling it!
This blows the doors off any history class I slept through. Written, and narrated so amazingly too. Hoping one day you folks will do a " What Will Earth Be Like In 4 Billion Years ? ''
Very hot.
Beautifully done. The Acasta Gneiss might truly be the oldest rock to be found. It does include zircons, which themselves had to be formed prior to that. Mind this: in Australia there are zircons that reach back probably 4.4 billion years, much much older.
For zircons to form, the presence of some water in liquid form is needed. This means that at 4.4 billion years ago, the surface temperature on Earth had already dropped below the boiling point of water. It may have gone up and down a few times (late heavy bombardment etc) but new scientific evidence shows that the real hell lasted for maybe only the first 100 to 130 million years.
Then again: your movie skills, narrating and feel for creating a good documentary are top.
Thank you for this comment, I was a little confused because they said in a different episode that Australia had the oldest rocks. I thought, these people need to get their stories straight.
can i ask where you got that information from? id love to read more
sorry let me be specific, about the history of the world..i didnt realize we knew "so much" about it.
@@9mmsafetyalwaysoff00 This professor has several hour-long lectures on all the ages of earth, beginning with the Hadean and Achaean that I’ve linked here. They are very in depth, college-level courses but really good and informative. If you go to his videos and scroll down, he also has videos on the Big Bang and formation of the universe, and the formation of the solar system. Several dozen hours of information. Link here:
ua-cam.com/play/PLbAWi3dWGVyPU6t-eK2kjZCgkiiqcKnZ6.html
The air pressure was far higher back then, so the boiling point of water would have been much, much higher.
WHY DOES THIS CHANNEL NOT HAVE A MILLION SUBSCRIBERS?!
Give it a little time! :o)
Because Carona
cose idiots is 97% ,they watching kardashians,,,
Working on it!
Because it’s not even a month old.
a tiny zircon Chrystal found in Australia is the oldest rock fragment ever found on Earth - 4.375 billion years old, plus or minus 6 million years.

This is SO COOL! You turned a boring looking rock from part of the timeline in a school textbook into The Last Survivor of the Hadean Era. Way to go for reaching my anthropomorphizing monkey brain! Also, thank you for covering this period of Earth's history at all! A while ago I was compiling a chronological playlist of UA-cam history videos and there was a distinct gap in the very beginning where I couldn't find anything like this that was any good. Props to you guys for bringing a more complete historical perspective to UA-cam.
What an amazing project. And you covered over 500,000,000 years in under 22 minutes. Thank you for this.
Thanks for watching! Appreciate it. SO much more on the way
Discusses a 4 billion year old rock. Keeps me here for 21 minutes. 😉😉😉
Little Jenny Come on, even the Serbian guy liked it 👆! WAAAAH!
Thanks for watching !
@@GeraBrown Jenny is just joking she has the same since of humor I do. Me and Jenny are going to get married and go watch another video for 21 minutes then get a divorce.
@@davidbrown8303 Thought she might be. Hence my response. Congrats. Um, I think, and regrets if the second part is true!
Leila Battison, truly incredible work you've done here. May your name go down in history with the likes of Carl Sagan as the greatest of science presenters for writing such phenomenal documentaries. My hat comes off to you.
Absolutely. We gotta try and get Leila and the history brothers on the Ezra Klein show! Get some powerful visibility!
I’ve watched hundreds of videos on geological history, some better than others, but yours have by far the best “wow factor” to them. Keep it up, I’ve got a lot of popcorn to go through!
Any geological history channels you can recommend? I'm a fan of EONs as well.
@@Inignot12 Check out Nick Zentner. He's at Central Washington University, but explains geology in everyday terms. I really enjoy them.
What the heck Man I don’t even know what words to use to describe how dope this was. 🤙🏽 cant wait for the next episode
Glad you liked it! We can’t wait either
My life long pal Kyle does the art for this video his work is amazing. very cool so I'm gonna take a watch. already a supporter here.
Stunning. I have watched many, many documentaries, and this series is shaping up to be one of my favorites. I cannot wait until the next one! Such great work. Thank you!
Thank you! We’re really pleased you like it
I feel blessed to have found and followed this channel from the beginning. Awesome!
Welcome! :)
Gneiss
same this is amazing
All I can say is Wow! What a fantastic Job you guys do on your Docs. I enjoyed this more than Discovery and Nat Geo shows with high budgets! Perfect for CuriosityStream and Magellan channels. They all should be knocking by now!
It is better here at the open UA-cam. CuriosityStream and Magellan channels are only for subscribers.
I love both episodes so far. I'm sharing them with my daughters. I love the intense, inexorable delivery and the opulent metaphorical flourishings which serve to bring a long-dead past to breathtaking life!
Thank you !! We appreciate the comment
Such a fine compliment.
A bit OTT I'd say, your opulent language. As for the history of planet earth, the grand description is rather reductive. But a good attempt
@@nedkelly8495 Of course you would since you're a muhfkn worthless troll. Not even a halfway decent attempt at being a human being. 👎
@@HistoryoftheEarth Please take out your garbage 👆. I've had all I can stand of these filthy YT trolls. I may be poor but I'm better than garbage that does nothing but barf all over polite commenters.
This feels like a lore video for warhammer or something like that. I love it.
The absolutely lovely poetic narration of this was as unexpected as the Spanish Inquisition
I’ll say it. This already is my favourite UA-cam series. Brilliantly done ✌️
Thank you!
Another piece of scientific art! Your content is gorgeous and informative!
Thanks so much
This channel has changed my view of what documentaries are. The narrator is perfect combination of facts (based on the most accurate knowledge we have at the moment) and excitement. Rarely if ever have I been both so entertained and so well informed at the same time. Great documentaries, I hope you keep making more of these!
So glad I stumbled upon this channel while randomly searching up documentaries on earth’s history. Your use of literary, elevated language and metaphor mixed with facts truly captures the grand scope of these events and it’s something a lot of science documentaries could stand to use more of. We humans do love a good narrative. Or at least I do :)
I love this channel, such good quality. you don't get good documentaries anymore. I've been on a binge on this channel since I found it.
This is such a good series. It brings life to times that had none, and there was obviously heart and soul put into this. Thank you🦋
Ive been interested in geology of the Earth and astronomy for years. You have brought them together the absolute best on line!
As a Geologist, this is eye (and hear) candy 😍
It’s pretty Gneiss
Wow! High production values, professionally edited, very informative and factual, absorbingly presented etc.. Is this what the "History Channel" should have been?
Thanks for watching! SO much more on the way
It's what The History Channel once was, before it was bought by Rupert Murdoch, who thought that scholarship was scholarSHIT and turned it in a piece of cable-shit.
@@JMDinOKC You got that right!!
The writing, narration, production, was top notch. I even learned something I did not know about the lost history of earth, wonderful work.
This is the kind of thing that used to be on TV before it all turned to garbage. 10/10 well played, sir.
In fairness to the history channel, it's hard to make moonshine in a Hadean environment....what are they supposed to do?
Short answer : Earth was pretty much exactly like Venus is now . Good job on the new channel 👍 Subbed and tweeted .
Thanks for watching and sharing! Appreciate it
Exactly what I thought!
Not really. Venus has a very thick atmosphere. What I can gather is that it was once covered by an ocean very much like ours, but that it boiled off and escaped while volcanism replaced the lighter gases in the atmosphere like oxygen due to the lack of a mag field, spin and tides. So basically it is as if our oceans moved up into the sky and got replaced with sulphur and CO2, while our old atmosphere vented into outer space. Then we almost stopped spinning, before the moon left us and took the kids. Fortunately nothing like that has ever happened here, nor is it particularly likely to.
@@politicallycorrectredskin796 It was probably more like Io than Venus near the beginning (although still without the atmosphere), but there's probably really no comparison in the current solar system which would really be similar to Hadean Earth. Once you get to know each object in the Solar System, you really get to understand just how unique each is.
Your dramatic stile is so beautiful and immersive.
A good up-to-date teaching tool for Earth 101.
Thanks for watching!
That was well above average writing, no kidding. And THAT is coming from an occasional (when its deserved) heckler. Rock on!
I cannot believe how woven together so many different observations and facts are in this video. Truly an immense amount of work, care, and passion has gone into this and I am so happy I get to experience it.
Nicely done. I've not heard such a clear description of this period of time before. Usually, it's glossed over with mentions of Thea and the late heavy bombardment in order to get to the conditions for the first life. Looking forward to the next instalment.
I am blown away by your brilliant productions . I had this playing randomly in the background (praise the algorithm) , stopped what I was doing , and started to watch . I thought I was watching a high quality BBC documentary until the credits ran . Well done guys , keep up the great work !
Subscribed .
If you were ‘standing’ on earth when Theia approached that must’ve been a terrifying site. There’s a CGI of the event from a television special that is kinda scary to watch lol. That and seeing the new moon forming literally right above the horizon racing across the sky must have been amazing to see. Such a fascinating time period
yeah but nobody saw it. There werent even any animals or plants around to see it. It just happened with nobody seeing it. lol
@@bradhirsch4845 Maybe we can witness it happen to other planets that are forming eventually
Bravo! What a magnific video! I'm astonished! Great job, dude! Keep doing more, please.
Thanks very much we appreciate the comment !
Well done:). Its too bad we didn't have this to watch back when I was in school in the mid 80's and early 90's lol.
Thanks ! Appreciate the comment
Tara, be thankful for what you had. I was born in 1948 and remember when my Dad got the National Geographic in the early 60's. Every space probe and new discovery of the Solar System, Earth and Mankind was greeted with amazement in the monthly pages. I've never lost that amazement as each day seems to bring with it new wonders. Including this platform that allows me to communicate with you and thousands of others around the world. Peace and Love dear.
Great channel. I really enjoy the line drawings. They look like a comic book but also very scientific and imaginative. Great job!
The writers and producers of this series are incredible. Thank you!
I really enjoy watching your channel. The images are amazing and your narration i find easy and enjoyable to listen to. It helps me to unwind.
Excellently fleshed story that serves also as a great summary and reminder of what I learnt during Historical Geology :) just one important correction: we can only talk about "Tectonic Plates system" in the Proterozoic Eon (2.5 billion years ago onward), as how stuff worked on earth before that was... Astoundingly chaotic and fast, a completely different style altogether. Worth its own video, may I add!
Awesome video. Have you seen that new study postulating that Theia was an icy body from the outer solar system and that is what brought our water?
Glad you liked it! We may be looking into that in one of the next episodes
I like it and before I watch it I share it with my friends. So they see there are some good contents on UA-cam that worthy to watch 👍
Glad you like it
This is absolutely awesome content for a UA-cam channel. The scripting and narration are of broadcast quality and far superior to the awful reiteration of Nat Geo and the like. Fabulous story telling which is really engaging, you have really worked out the golden formula. Well done all. Gonna subscribe, catch up and probably pace up and down until you release more content.
Excellent and succint video. I'm a geologist and I'm really impressed with how detailed you made this whilst still making it accessible to everyone. Excellent focus on the sources of evidence for these discoveries. I'm looking forward to the Archean - because I love the Outer Hebrides and Greenland. Maybe after this ambitious project is over you could focus on some topics in cosmochemistry (solar system formation) or do some accesible videos on ore deposits and isotope geochemistry?
Hi, as a geologist do you have any view on how important or not the Theia collision with early Earth was in terms of allowing for the emergence of biology?
@@alexanderplatypus3664 That's not really the subject of geology, but in any case, some studies have claimed that without our moon (formed by the collision with Thea), the earth would have had a rotation and days perhaps too short to allow for complex intelligent life. Then again, as the narrator often says in this series, "life finds a way"
Leila is such a good author and researcher! It is a great pleasure to see this degree of thoroughness.
I've always been enthralled by our Earth's history, but I nowadays do not have the time to sit and read books like I once did. So thank you so, so much for this!
2 things could up your game... put some acoustic absorption or blankets behind the narrator (where the mic is pointing, assuming you’re not using an omnidirectional) to cut down on room reverb, and paste your script into the subtitles. Awesome stuff!
Wirting this comment for the future, when you got over a million subs. This channel is amazing! Please keep it up!!
Thanks for watching! Plenty more on the way
How amazing is it that we're even here to watch this? I love learning about our beautiful planet and its journey through time.
Canadian Shield is my home, I grew up on some of the most oldest rock on Earth.
It's unique and beautiful, I love this place.
Funny fact :
When I was young, I licked those Rocks.😁
Absolutely fantastic. Narrated so eloquently and informative, well done.
Science into poetry and back again. Brilliant.
Wow! Not what I expected. Intriguing intro with gneiss and the Canadian shield. Ironically, I'd been wondering about some rocks I found recently in the Sierras above Pinecrest, CA. I was curious about what formed this rock/gneiss, now I know. Although, I found out that the age of the Sierra Nevada range is much, much younger than 4 billion years old.
This us great work, thoroughly enjoyed. I look forward to the series and will share. Mahalo! 💜🌎
As a Canadian I understand the difficulty in finding remote images of the Canadian shield in the north but when you label the western cordillera as the Canadian shield you need to do better.
Great narration and love the artwork that goes along with it!
Thank you !
Jenniferocious - love that name!
Thanks! Yours is clever!
This is exceptional. The subject is easy to make interesting but just the right amount of theory should be injected. You have done an exceptional job in this first episode. H. G. Wells would be proud to put this as chapter 1 of the Outline of history if he was writing deep history today.
I am absolutely loving this channel as I watch the series from the begining. The work is on par if not above the same professional videos they show at museums and planetarium
This doc is a step above others. I enjoy the details.
Education that’s effective for everyone to learn from is very welcome and encouraged💛
The moon is not drifting away, it is being lifted higher each year by its increasing orbital energy, which is subtracted from the Earths angular momentum. The moon is forced into a higher orbit by its tidal interaction with the ocean, causing the length of the Earths day to increase by slowing its rotation.
Glad I came to the comments to check for any corrections. Mostly the facts of the video seem quite solid, but I guess there are some acknowledged slip-ups. Can I ask where you learned this? What a cool bit of info!
You’re arguing semantics. NASA says it’s “slowly moving away”, so the layman is fine using the term “drifting”.
@@jordanfarr3157 Physics general knowledge/orbital mechanics, probably about 15 years ago from space sites/wiki possibly. Was interested in calculating the power drain from Earths rotation which came out very high about 50,000 GW if I remember correctly, probably more than global energy consumption. Cheers.
Well done. Cant wait for the next episode.
Thanks so much. We can’t wait either !!
I cannot ever hear enough of this so interesting and mysterious times. It is so unbelievably long ago and I would LOVE to see how it actually was in those eras. Thank you for making these wonderful videos!
I have always liked these kind of shows on TV back in the 70's & 80's. A few were pretty good & interesting. Kelly brothers and team here are world class documentary makers. These are the best, most reliable, super interesting & informative documentaries I have ever seen. I know all this stuff and I am glued to these as if I know nothing but an super into it. Thank you. I liked & I am subscribed on all your channels. 😃
This is such a delicate & lovely series, I’m blown away!
Peggy's cove NS Canada is a beautiful example of glacier smoothed (huge) rock formations, I've been trying to find more info on its geology since visiting the first time in 2017. Theres a pretty cool rock carving there as well as its in the granite, quite large, done by hand tools n quite detailed
I love all your channels! And this one probs going to be one of my favorite, I have high interest in geology and history so perfect 💛
Really good lads thanks
Thanks for watching !

God created the Big Bang.
How to appease both sides. Or.. start some war.😂
@Mister Myxlplyx Yes it is. Religion has slowed the progress of humanity because people think some magical floating man created everything and to be content with life today. Politics who are almost alway religious want to force that into their education systems, which inevitably lower the acceptance of science over the easy way of answering tough questions by saying that god made everything and thats just how it is. Over 2 trillion galaxies exist in the known universe, each with hundreds of billions, some even trillions of stars. But people out there think that some magic deity sits around one small and average star that has a life bearing planet and judges someone for the most insignificant things. Its absurd and it absolutely does affect every person on the Earth. And not in a positive way. Go around looking on these types of videos and you will find people who deny all scientific facts, claim the earth is 6,000 years old and that the first humans were a single male and female who just so happened to form with enough intelligence to speak a complex language. These people also believe that their god created light before stars and other celestial bodies. That he had human and dinosaurs roaming around the same planet, at the same time. Denying facts over fiction is not a problem to be placed in the backburner.
@@tylermoore2764 Exactly! It's reckoned that the medieval Catholic church put science back a thousand years due to its interpretation of the Bible!
They're here.
I think these videos are going to be my bedtime stories. My favorite topic by the most soothing narrarater

Keep it Up Guys! I love your Content!
Thanks ! Much more on the way
I think they're well done. Thank you for making and posting these. I have a piece of Acasta Gneiss. It's my most prized geological possession. Greg in TN
Your poetry reminds me of the creation stories in the Old Testament. Beautiful, thank you.
Narrator: "This is what geologists call a gneiss"
Me, and intellectual: Ha, nice
Nice gneiss, Onyx!
Sorry, I mean Ony lol.
1:35 "This is the Canadian Shield." No. That is Peyto Lake in Banff National Park, just off Highway 93.
Yeah...I was looking through comments to see if anyone else picked up on that; The Canadian Shield is no where near the Rockies, which they show several times while talking about the Shield, so exactly where did this research take place?
I came here looking for this comment. It was really jarring to see that. The Canadian Shield is old, really old compared to the Rocky Mountains. All the hills in the Shield are worn down and rounded.
Yep...gave up watching at that point.
@@alibaba855 You have ridiculous standards
That bothered me too. Mountains tend to be-by their very nature-young. The Canadian Shield is old in large part because it has not been disturbed by plate tectonics and volcanism. The area of the Slave craton, where the Acasta Gneiss is found, is scraped nearly flat, and there are no mountains to be seen in any direction.
Mate, this is some beautiful work you're putting together. I love your channel. This is amazing quality.
Great video. If you are an enthusiast please visit the Kirkland Lake, Ontario area. From Matachewan to Larder Lake. So many archaeon rocks. Rock cut's have gneiss, lamprophyres, copper, nickel, iron (on the railway bridge cutting about 5km from KL), fyi on the north west and east about 100M from the bridge is a spectacular outcrop of chalcopyrite. I'm not there anymore, an avid prospector at the time. Oldest rock 2.9bn, after the right turnoff at Hwy 11, rock on the left before the bridge, about 2km. Volcanic bombs, (geodes) are in many rock beds, try left anywhere around Lake Sesekinika.
Excellent channel, one can see passion and dedication! The only remark that I have is the actual vocabulary used. For non native speakers it might be too complicated to understand all of the nuances, I usually understand 95% of content of the videos with this subject, but with you guys I am down to 80%. Won't stopping me from watching though. The improvement you could make is adding the captions - currently there are only auto generated ones, but they are not perfect. Looking forward to new video. Greetings from Serbia.
Thanks for the input Stanislav. We will look into this for sure!
@@HistoryoftheEarth dont dumb it down please it is very difficult to find information like this that is not on a 1st grade level
Hi Stanislav, brother from another mother.... just FYI he‘s using very poetic language, it‘s lovely and you don‘t find it every day, but it does mean that a lot of native speakers would also be a little unclear about some of the vocabulary
I beg you, both History Brothers, do not dumb down your narratives on any of your films! Non-native speakers can rise to the challenge, and their English command will grow and grow, enriching their lives. It's nearly impossible to find science films for the general public that are not dumbed down; this is a primary asset & attraction of your films.
Lichen is pronounced like: 'lie - ken'.
Thanks so very much for your very hard work and your valuable time!
6:44 500 billions years? I think you need to annotate a correction there, mate. haha.
yeah i was confused there too and what crystal were they referring to.
If only the fuckers didn’t remove annotations
I came just for this comment... I wasn't disappointed
@tony baloney Didn't it happen about 14.7 billion years ago?..give or take.
@tony baloney The quibble was about 9.7 billion years :-)
Just awesome! Thanks for posting this terrific content.
Dude awesome presentation I’d watch this stuff all day subscribed and waiting for more. Quality.... Dope.
It really is mind blowing to think of a rock that has been around, continuously, for 4 billion years, and has seen every single event, great and small, unfold. From its perspective, humans just appeared a few minutes ago.
Brilliant, carry on.
So much more on the way :)
History of the Earth can’t wait!
That was a very gneiss video!
An epic tale about Earth's geology. As an amateur geologist I'm in love with your channel now 😍
Really good. One nitpick, when the narrator says "this is the Canadian Shield", the shot is in Canada, but it's Moraine Lake in the Rockies, which is not on the Canadian Shield and is very geologically recent. Canadian shield is more like Ontario and Quebec and Hudsons Bay, not Alberta.
There is also a deposit of ancient rock in a deposit near Porpoise Cove, in Quebec. There is some controversy as to the age of the rock, though some estimates run as far back as 4.32 billion years old (though some analyses say 3.70 billion). It's nice to know that some bits of ancient rock have managed to survive the eons.
