Does the Bible tell us if there is life on other planets?

Ponder this: Jesus ascended through a cloud (Luke 24:50-53; Acts 1:9-11).  But what if Bedouin nomads on their camels in the desert saw this from a distance and said to one another, “Look, what is that? and “Uh, I don’t know. It must be a UFO.”  Further, what if other observers only saw two angels from their vantage point and thought that they were some sort of alien life forms? Just because we don’t know what something is, it doesn’t mean that there is not someone else that does.
