Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.
Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life.
Perhaps, as some wit remarked, the best proof that there is Intelligent Life in Outer Space is the fact it hasn't come here. Well, it can't hide forever - one day we will overhear it.

I believe that there may be intelligent life on other planets.
