why haven't they yet?? maybe the have??

start going down the rabbit hole at that point.

but personally, i'm on the "universe is way too big for it to be just us" train.

intelligent life out there may have taken a different path towards intelligence. maybe humans are the only ones warring with each other. another species might have the key to existence that doesn't include conquering and colonization. that's life as we know it, but what about unknown life?
