I'm agnostic (or an agnostic, if nouns and adjectives confuse). There is no evidence for a god, or gods.
Man cannot explain the universe (s)he sees, and therefore invents a god who "made it all". It's easy (and lazy) thinking.
All gods rely on "faith". That is to say that they don't have any evidence of their existence to put to you. You have to blindly "believe".
That does not mean you should disbelieve. I'm not a god. I cannot tell you what to believe.
(Don't expect to live on after death at the behest of one god or another though , it probably is not going to happen)
