You ever think that maybe we are the only civilisation in the universe, and in the far distant future once we have finished nuking each other and end up colonising other worlds (which is going to happen one way or the other) eventually we will evolve into different races, making new species of intelligent life!
Of course this will take another 100, million years for that side of evolution to take place but its worth thinking about.
And here's one for some of you... when a UFO is spotted and its claimed its an alien, you ever think it could be a visitor from another time zone (yup time travel) or parallel universe's checking in on our progress of evolution, ok i watch to much star trec but still it make more sense then some one saying were not alone or wait are we, look around the world we have, how many species of animals are there, to many to count i imagine and were still discovering new ones daily, and the ocean is still a majority mystery!. Perhaps there are millions of intelligibly civilisations out there, just there all on this planet, maybe its not intelligence in the way we think, for all we know dolphins may think were primitive!
