astounding that, in 2024, you still have geniuses like yourself saying things this ignorant. Humans were not around when the asteroids hit, and if we were, we would not have survived. Same goes for most of the other calamities you listed.
I don't know how you can claim we, a global species that can inhabit any land mass or climate, wouldn't have been able to survive. We did survive ice ages with stone aged tools.
"Beginning 195,000 years ago, the global climate entered a period of cold and dry conditions that lasted for 70,000 years, a phase called Marine Isotope Stage 6. In interior Africa, this shift triggered drought conditions so severe that much of the continent would have become uninhabitable. Genetic studies of modern human DNA tell us that at some point during this period, human populations plummeted from more than 10,000 breeding individuals to as few as 600. Homo sapiens became a highly endangered species; we almost went extinct. This “population bottleneck” means that all humans alive today are descended from this tiny group of survivors. The result: our species has less genetic diversity than a single troupe of West Africa chimpanzees." (https://www.cbc.ca/greathumanodyssey/content/iceage/135k/ind...)
Insane that this has to be explained to people.
