Extraterrestrial civilizations. What is your opinion?

I'm not denying that there are other civilizations in the universe, and in some cases, I even support that idea... But the fact that a guy was talking to GOD? :D Even the appearance of an angel isn't given to everyone. And here – boom, GOD:D

I know what Ganymede will write now: "But how do you know, maybe this is a unique case where God himself appeared, maybe this guy is a prophet" or something along those lines. There are so many "prophets" who have "talked" with God, you know:)
