Replying to Life after death...

Just wondering your thoughts on life after death, and life itself aswell. I believe that either we are all just different spirits, and there is no god, or higher being, just life and science itself, or that I am the only conscious or spirit in the world and that everyone else is just a perception, almost like a dream. and about life after death, i have no fuckin clue. I want to believe in heaven and/or hell but its just not realistic to me.. give me your ideas.
