No I'm not religious at all. I do think it's likely there are powers far greater than us, it's statistically likely. If we're the top that life has to offer it's a pretty sad affair.
But I think it's extremely unlikely they would give a rat's ass about what we do or believe.
If by "powers" you mean "civilizations" then yes, it is likely that there are many. Whether they share anything with us (not only technology) is a matter for debate.
If you mean "we are in a simulation" then maybe :) I like to think we are the end-of-semester program in a high school.
And for the last one I do not know, I would prefer everyone to leave us alone.
If yes you are already worshipping and imaginary concept. At least with aliens you would have some kind of connection with reality.
If not the word god is not really a part of the vocabulary.
