Life after death?

The subject isn't as contrived or as nearly cut-and-paste as you've made it seem. You're taking the angsty 14 y.o, sitting around a couch, getting high while diving off into the "i'm trying to appear edgey" approach.

There's tons of theories surrounding the very existence of life, reality and conscious and the majority of them have nothing to do with faith or your belief in any sort of metaphysical deity. If the extent of your understanding into the topic only goes as far as "there is no life after death" aka the Trump approach. You should probably just stick to CS:GO and Mountaindew.
