How cool would it be to live on a completely different planet!

So, it's only 600 light years away... But it's a huge possibility of maybe one day living on another planet!  Kepler-22b, is very similar to earth, in size and temperature, but that got me thinking... Earth went through many different phases and changes, at what point would this particular plant be, if we actually found life? I've never believed in aliens one bit, okay let me clear this up... Aliens as in what media portrays them to be... but life that could be similar to what we see on earth; there is every possibility. The day that star trek, materializes and we boldly go to seek out strange new worlds will be amazing! We just need a brilliant mind to figure out how to traveling at the speed of light!
