I don't have a problem believing in God and Jesus. But in Genesis one has to wonder about these sentences that just go on and end without finishing. The thought is unfinished. Where did Adam go? What is he doing? Hello? There has to be some pages missing.
I would think flying would be pretty cool. You would be able to fly away from all your enemies and get where you're going much faster. But being invisible? You probably wouldn't use that for the good of man.
