No, it was no UFO on the moon, but Buzz thought that he saw it, and that is completely different.

And when we were getting ready to leave the moon, Houston said, "Apollo 11, you're cleared for liftoff." And I said, "Roger, we're number one on the runway." Although it's a phrase used over and over, there was no one else up there, and there wasn't a runway up there either.

Don't you hate it when you have to explain a joke.......

From the article (BA is Buzz Aldrin):

RE: Are we alone in the universe?

BA: Well, that's hard to say. There's absolutely no evidence. But [space] is so enormous, so vast, there may be rudimentary forms of life developing in many places--thousands, tens of thousands, millions of places.
