religion and belief

I believe that there is a reason for our lives. If I didn't believe this I don't think I would stay sane. However as to what that is I have no idea and am open to suggestion.

All religions are wrong. They must be wrong, they were created by humans and humans are a flawed existence (yes, we are flawed, we are greedy, jealous, and overall most of the time ). Additionally, let's say this "god" entity exists. Then it would be an extremely high developed existence, far too high developed for us humans to understand it (even for just one little bit).
