298,000 of those years didn't have toilet paper. It was utterly impossible for a single person to "end humanity" even 200 years ago; now, the president can do it in minutes by launching a salvo of nukes. Comparing the present moment to the hunter/gatherer days is preposterous.
It’s absurd and not scientific to claim that "a salvo of nukes" will kill humanity.
We don’t know how this will play out. It never happened before. Same with the chicken above.
For pretty much every single person you or I personally know, that would be the equivalent of the end of humanity.
Let’s not nitpick here. Worldwide human suffering and tragedy is equivalent to the end of humanity for most.
We can sit here and armchair while in the most prosperous, comfortable era of human history. But we also have to recognize that this era is a blip of time in history. That is a lot of data showing humanity surviving sure. But it’s also a very small amount of data showing any kind of life most would want to live in.
