I don't believe in alien and ghost "sightings". But I really doubt there isn't some kind of life, even just single celled life, considering the billions, trillions of other planets out there.

Ah, I can understand bacteria being on other plannets but not aliens. 

But again, it's not billions, trillions, it's hundred billions of trillions... in the visible Universe. And the full Universe is at least hundred times bigger than that and possibly infinite.
