The only question that seemed even remotely serious is your fifth one.
-How did humans survive the K–Pg extinction event that killed the dinosaurs?
The great dinosaur extinction was not total. There were pairs of each kind which survived. Of course the vast majority of all animals died as well as the vast majority of people. They died during the world wide flood of Noah's day. Even biologists discovered there was a major bottleneck in present animals. They reject the obvious, but do accept it happened.
Apparently the change in climate was too severe for most of the animals to survive. I read recently that 90% of all known species are not extinct.
