I think that anyone who believes that humans are alone in an infinite universe must be extremely narcissistic. For one thing, if us humans are the most intelligent life in the universe, then I please, someone call Kevorkian for me because I am totally ready to leave this life for good...there would be not point in going one because...in the grand scheme...we humans do some stupid *** **** for real. Second, its pretty self righteous to think that in an endless universe that no other intelligent life could have possibly developed anywhere else...so yeah..I totally believe there are aliens out there somewhere...
