There could be an afterlife. But I can't answer that one way or another. I believe that anything is possible though. I just don't think that what I was taught growing up, when it comes to christianity, makes any sense at all. Sounds.... this may seem harsh.... INSANE.
So, I could go on to be what I was before I was born, I could turn into a talking mushroom, or burn in a lake of fire, or go to a heavenly city in the clouds (depending on if I was saved and/or met the standards of the god of that city).... Maybe we're all apart of a reality tv show to the aliens and when we all die, we get recycled by the aliens so they can put us back to work. For the lulz, you know, on the reality show.
