The problem here seems to be that you're combining two ideas
1) That aliens exist
2) That aliens have visited us
Those are two very different concepts.
Aliens may very well exist. The next closest galaxy (Andromeda) is 2.5 Million light-years away. That means it takes light 2.5 MILLION years to get to us. So what we observe from them is ancient history, not current events.
Even in our own history, 2.5 million years ago was BEFORE modern humans existed. So they could very well be looking at us and seeing no sign of intelligent life either, because they're not seeing us as we are today.
So seriously there's no way to accurately tell if life has now formed on other planets in other galaxies.
As for aliens visiting us... I think it's interesting, but I'm undecided.
I *do* think UFOs exist - but only because ANY unidentified flying object remains as such until you identify it. *evil grin*
Sure sure, people now like to equate "UFO" with "alien" but really it's just something flying in air or space that hasn't been identified yet.
Do you believe in aliens?
