Sometimes we get too smart for ourselves.
I've heard people say that since we humans want there to be something for us after we die, somewhere great, it would make sense that we would make that up and thus, it can’t be true, because that would just be too much like something we would want to be true.
I don’t know if heaven exists or not. I do know that just because I want it to and it seems like a great idea, is a terrible reason to believe it doesn’t.
The same could be said for everyone on this planet having a decent life. Well, of course that can’t exist - that would be too good. It must be unrealistic.
Just because there are these seemingly unattainable dreams, doesn’t mean we’re all fooling ourselves. It could mean we’re all being drawn to something more good.
