I'm not sure why you're asking yourself these questions, other than it tends to support my theory that you're all schizophrenic to begin with, but I'll intervene and answer them for you.

There might be a God. I won't deny it. I have no way to know what exists outside our universe, or if there is an "outside our universe". At the same time, living my life based around a book claiming to know something about the unknowable seems particularly absurd. I base my life on what I can see and feel, not on the hopes of pleasing a "person" for whom there is no evidence of existance.

Same can be said of extraterrestrial beings, though many fewer people base their lives around little green men.
