Great posts guys, thanks for sharing all the experiences. I wish I could say I had any sort of interesting unexplained stories at this point but sadly I don't.
I, like the rest of you definitely believe there is life on other planets and given the age of the universe it is tough not to think that another species may not have evolved before us and therefore be more evolved then us. With that being said and looking at our current rate of technological development one wonders where will be by 2050? 2100? Of course assuming we don't <insert world ending situation here> first.
Lots of great theories out there about them and some very interesting TV shows.
