The Fooby Paradox of Space Travel

i think the strongest or i should say least weak camp is the idea that that intelligent life is probably just very rare nobody else in our galaxy yet and maybe no one else super cluster though our super cluster. don't they around  and to for me himself it was no paradox he helped make the yalam bomb and there was no space race when he died hadn't happened yet so he just assumed that space traveled other wars was virtually impossible, post moon landing a guy who coined the term for repair docs said civilizations tended to blow themselves up first post moon landing.
