If "God" exists as some sort of life, then yes he would have to fit within the scientific definition of being "alive" so it is also a scientific question, yes. But in order for God to be proven to exist, in the scientific sense, would require a pretty seemingly unlikely set of circumstances.
I'm prepared to accept either outcome, there is a God or there is not a God, as the truth. But I hope to wait about 100 more years (give or take) to find out the answer!
I'd much rather discuss/observe that dancing pole sometime. Though if one comes with the other... what an interesting date that would be.
