Astronomy is one area of science that has always fascinated me, as well as the accompanying physics.
I look forward to the time when we have a colony and mining base on the moon. I am an avid fan of exploration and think the U.S. should put more emphasis on practical technological development, though NASA could use a little stream-lining.
Perhaps eventually we as a civilization will develop and explore to the level portrayed in the various Star Trek television shows.
And like a large percentage of the general populus I do think there is probably other intelligent life in the universe. Let's face it, the universe is a very big place and it would be extremely arrogant to think God created life on only one planet.
Now as far as whether UFO's have actually visited the Earth; there seems to be some amount of evidence to support that opinion, but who knows.
