i dont know why people think there is a paradox. the way that life springs from barren rock is not known. if we dont know how that works, then we cant assign a probability to it happening on a given planet. people just assume that the probability is very high. it could be next to nothing for all we know, small enough so that even the entire universe only produces one. the paradox is all based on huge assumptions. there is no paradox until we prove that the probability is high.

well thats not true, because you need life but you also need intelligence. and again, everyone assumes that if you have life it will eventually become intelligent. and people assume that if life is intelligent it will eventually build space shuttles. its all a huge, huge assumption. look at all the animals that qualify as intelligent. some birds and monkeys are hugely intelligent, but they dont build space shuttles. this shows that intelligence doesnt equal space shuttles and that even when life springs up, and even when it becomes intelligent, it still could be super unlikely that it will build space shuttles.

hell, there are even humans that might have never built space shuttles. there are indigenous communities all over the planet that never developed technology and probably never would have. when you live in a warm climate and food is abundant, there may never be a reason to.

it is unproven that it is likely at all for space-shuttle level intelligence to spring up from bare earth. there is no paradox. its probably just really unlikely.
