It’s a logical extrapolation if you think life is a natural phenomenon. It would be exceedingly weird to see no evidence for it, but of course we have not been looking long or far.

And yes, space flight is brutally hard. Look up the history of sailing. Look up the Polynesian indigenous peoples and how long that took, through multiple waves of exploration, or the people who walked across a land bridge to North America during the ice age. Space flight is easier and safer than some of those feats, given the tech they did it with at the time.

If there is a fantasy it’s the idea that we’d have bases on the Moon and Mars by now. What we are doing today is the equivalent of early Polynesians hollowing out some logs and going fishing.
