I actually do believe in extra-terrestrial life and that the universe is full of it. I just dont believe the aliens theories that apply to every damn thing that we dont have an answer to. And I dont believe they have visited us in spaceships. And if they were to 'visit', the universe has probably trillions of other interesting spots they could choose from, and I would think they would 'prioritize' what and where to explore. We must be so full of ourselves if we think we're more special than everything else in the universe. And if they did come here, why do we have to assume they will use spaceships or even be in physical form? We only seem to think in OUR terms of how WE would go about doing things. Aliens may do things entirely differently. Maybe they would have developed beyond any technologies we could think of and mastered other areas of knowledge that are so far beyond our own that they dont need physical travel to explore far off places or planets such as our own. Maybe they could even project FTL conscious energies and be anywhere in an instant and know everything about the place they project to. Far fetched? Hey, nothing can be more far fetched than the existence of the universe. If it exists, ANYTHING is possible.
