Good post, mate, although it made my brain hurt a bit...
I truly believe that there is life on other planets... I don't mean that there are super-powers with massive spaceships, all ready to come down on our asses like in Independence Day (or 'V', a much better version of that same story... one for all you sci-fi nerds out there

) I just mean that this tiny little part of the WHOLE universe is all that we can see. I don't think that the planets we know about are capable of supporting life. But lets face it, we don't have the technology to investigate the other 99% of the universe...
And if they're out there, why is it assumed that they have our level of technology? It might the equivalent of 1945 or 1066 or, I dunno, some sea-based slugs trying to pluck up the courage to jump onto dry land. There are some worms wriggling about on some planet or moon, just outside of our telescopes, that we don't know about yet... yes, that is LIFE ON OTHER PLANETS!
To say that us silly evolved apes are the only life in the whole galaxy is like thinking if you drive far enough, you'll fall off the edge of the world.
Well, that's me getting all cosmic and shit...
