Is everyone so depressed now partially because modern science has probably proven there is no god / afterlife?
By that I mean, it must be an inherently comforting thing to think - we inherently know this and want there to be something after death, because it feels right, or more meaningful. There's a reason basically every civilization ever has some sort of afterlife ethos.
I realize I am basically horseshoeing my way into evangelicalism but still. Maybe life was better if we believed there was something beyond this. [edit - please note that yes, the world is shitty, things are awful and getting worse, and that is exactly my point -- we get THIS SHIT, and nothing else? god that's awful]
Figuring it out on your own is science, but I have a feeling OP didn't actually personally search the world for one-horned horses or pointy eared-people with long lifespans. I bet they didn't even work out how biology changes with scale and how evolution works to show that there can't be tiny winged people.
