So the Permian-Triassic extinction event doesn't ring a bell?
So we are to believe, based on your complete lack of understanding of conditions that existed during the pre-Cambrian, that mankind's future rests on our ability to survive in a such a world? Really?
By all means tell us what was happening in the Pre-Cambrian. I am interested to hear what you have to say. Be specific.
The point is, dumbass, do you truly believe that life as it exists today on this planet, particularly human life, can exist under pre-Cambrian conditions? Because you appear to believe that were that to occur, it would be a walk in the park.
I believe I AM THE ONE who pointed out that there was no free oxygen in the atmosphere during the pre-Cambrian dumbshit, so the assumption would be no, don't you think? Are you so totally incapable of thought you can't get there?
