Jughead has presented this same line of thinking before. What if we discovered intelligent life on another planet, what would the God believers say? Would it spell the end for Religion? Would the Bibleists go away and shut the fuck up? It was something along those lines, I can't recall exactly.
I do recall I turned the scenario on it's ear by asking; what if we discovered intelligent life on another planet and they worshiped God like we do? What would the God-deniers say? Would it spell an end to Atheism? Would bigoted anti-religious scumbuckets go away and shut up?
No, we have not had such a discussion. I would not be supprised to find "intellegent life" on another planet worshiping God as we do. It would be likely that IF humans invented God, other intelegent life would do so also. Humans invented tools, and even on Earth we find that other species also invented tools.
