Do You Believe In The Existence Of Aliens?

[Muiä]

Hey all,

I thought I would put this in the science section since it's one important question with scientific impacts. I'm not the most intelligent person but I do try to learn as much as I possibly can so anyone who can enlighten me is greatly appreciated. I recently watched a programme on Discovery with Steven Hawkins and he gave us his perspective on life beyond our own planet. I was fascinated with what he said life could be like, and lots of it unknown to us as life. The possibilities of life under martian soil, and even life that moves through space itself rather than living on planets. He certainly got my imagination going!

I believe that alien life is possible, if not certain. With the size of the universe and the age it has existed there MUST be other life out there. Even creatures like the Na'vi could exist or have existed when you look at the numbers. There is such diversity on our Earth, so imagine what could be possible out there! Maybe life follows some sort of rules for the environment it is in, so for a planet like Earth, life would evolve in a similar way. Bipedial, tool using creatures. They could be reptilian or even rodent like but the general form of intelligent life would look somewhat familiar. Life could be based on silicon instead of carbon, so their planet could be uninhabitable to us but perfect for them.

I like to think that maybe some civilizations are out there observing us but leaving us to our own folly's. It's nice to think aliens could help us but I think the human race is still young, with a long way to go. One thing that would make my life is contact with intelligent alien beings, but I think we may destroy ourselves before we got to that point.

What is everyone else's thoughts on this subject?
