But the important thing is that it gives the main ideas of evolution!

Well, it is more or less explained: a lot of chance and chances I think.
It started at the bottom of the ocean in the soup of water loaded with carbon and warmed by the volcanic tulips underwater. For the "more complex" life we needed the UV of the sun which made, among other things, H2O2 available after the glaciation of 15 million years ago 635 million years ago.
I did not know that there had been several other mega continents before Pangea, I wonder how we know it is so old !!
I also didn't know that complex life in the oceans (other than bacteria or microalgae) only appeared 500 million years ago. On the 24h scale this corresponds to 21h!

Then it took 120 million years to create the ozone layer and allow terrestrial life to develop from 380 million years ago.
If we fucked it up, we'll know where to go anyway
After there was a big reset (or almost) with the extinction of the permian: https://www.econologie.com/l-extinction- ... s-932.html which allowed the development of dinos ... the rest we know
But I learned more in 1 hour 20 minutes than in 10 years of history / geology / biology lessons ...
(I took notes, I didn't memorize everything but now I know)
ps: the doc also talks about a well-heated atmosphere after the impact of the dino, not 800 ° C but evaluated at 275 ° C (zon found a thermometer?) ... enough to make the big roasted lizard ...
