so, because some photos of UFO's are probably not aliens from another planet means there IS NO INTELLIGENT LIFE outside of earth? what an ignorant and narcissistic conclusion... just because they might not be as civilized as to make a flying object that can travel outside their own galaxy doesn't mean they're not there. we can't get send populated ships to any planets WITHIN our own solar system... that doesn't mean we're not intelligent or that we do not exist...
we will never reach the ends of the universe. we will never come close. to think that because we can't see it or reach it, means there is nothing there is very naive and self-absorbed
