When I was younger, I thought that pretty much all of the developed creatures died at that point and that the whole evolution from single-celled to multicellular creatures got reset and restarted. Which of course isn't true.
I think we should always try to be as accurate as we can, because facts already get distorted my time, thus there no need to distort them before they even meet time.
I believe truth and accuracy is important. But because many many people don't, we now have a saying: "History is written by the victors." Meaning history is distorted.
