Wonderful! Thank you for sharing how it’s done.

Excellent video

Great video, but I'd highly suggest to use a better microphone next time, because the autio quality is jarring for an extended video like this.

We know we got from supernovae and dead stars the calcium, we can get the iron and other elements.
But what we do not yet know is that we got our will from there.
The same essence that was eliminated in the upper light before what scientists call the big bang, at a certain moment was created. And what we see outside as plants, animals, and different types of human beings, these are just covers of a more inner essence.

Read the book Rare Earth, by Peter Ward. There is life just on Earth. Organizations like Carl Sagan Institute and SETI are wrong.
