With the vast diversity of life over the past hundreds of millions of years on Earth and the difficulty they encountered, I would bet anything that we are indeed aliens ourselves. Or rather that life almost certainly exists elsewhere in the universe.
Sedimentary rocks mostly form underwater. Many of them incorporate naked eye visible sea creatures as they form (limestone). The retrospective landmass arrangements the geologists display (like Pangea here) are predominantly put together based on rocks formed in the coastal and Continental shelf seas, and the fossilized sea creatures left in them.
I doubt you would even recognize Earth of ONE million years ago, much less the planet almost 250 times older! You guys always start out with "maps" that show the Earth of today (screwed around, but still in the modern shapes). I suspect Earth was flatter, with far less water (less than ten percent as much).

A real passion for history and sophistication to explain it eloquently!
Excellent presentation!
you showed a map of the landmass of that time. Did they had a north and south pool and snow. Was the weather climate different?
This is tragically underviewed.

Talk for yourself, short lived mortal. I remember it as if yesterday
