Life After The Death

Is life after death something people just came up withto not scare themselves for the realization of death?

I know death happens to everyone. I dont fear death itself. Like everyone, I fear what happens after death. I want to know, our main purpose on earth is to populate and keep our species alive, but why? Whats the point? Is afer life something someone just made up so we wont be scared to die? Is our brain concious after death? even though our brain dies? Why cant scientist figure this out? They know the answers to everything almost.
