Except the brain itself is concieved within the womb. Before that we were sperm and even then so before that we were nothing. So either way you take it, our aweness comes after we were created, be it the first instance after we were created as sperm or after when a brain was made up for us.
So no. There is no afterlife and BrainS would be right. I want there to be one, unrealted to any of the relegious bullshit, but reality is unkind. We will become nothing and honestly that's ok.
