Kick ass pictures.
Heres a paragraph from a book called Chariots of the Gods? published in the sixties:
"The Late Willy Ley, well known scientific writer and friend of Wernher von Braun, told me in New York: 'The estimated number of stars in our Mily Way alone amounts to 30 billion. The assumption that our Milk Way contains at least 16 billion planetary systems is considered admissible by present-day astronomers. If we now try to reduce the figures in question as much as possible and assume that the distances between planetary systems are so regulated that only in one case in a hundred does a planet orbit in the ecosphere of its own sunm that still leaves 180 million planets capable of supporting life. If we Further assume that only one planet in a hundred that might support life actually does so, we should still have a figure of 1.8 million planets with life. Let us further suppose that out of every hundred planets with life there is one on which creatures with the same level of intelligence as homo sapiens live. Then even this last supposition gives our Milky Way galaxy alone the vast number of 18,000 inhabited planets."

Our Milky Way galaxy is only a speck in a bigger stellar system that holds other Milky Ways. Its a little hard not to believe that there's life somewhere out there
