I usually stay out of these threads but I had to respond to this one comment that has nothing to do with global warming...OR DOES IT as "they" search for another planet to live on since destroying their own...
If anyone believes that we're the only "round ball"....mysteriously levitating in space....with a living population on it, or from it....you're living too far inside yourself. Think a little more outside the box. Consider how far aircraft have evolved on this planet in a mere hundred years. Think of where we'll be with space exploration behind people like Rutan's followers, a 100 years further into the future. A 20KB computer filled a large room in 1975 and I still have some tape reels from it......now you carry 30GB in your pocket or stare at it on your boat helm. Can you not envision "Warp Factor 5 Scotty" as a reality in the near future. Consider another solar system in a galaxy close by that's say a mere 500 years or even a 1000 years ahead of our evolution. They are there, and they have been here. A jet load of workers get delivered to area 51 every day to work and they ain't building cars.... Captain Wayne signing out... LOL
