The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations.



This thought is remarkably similar to the Fermi paradox If life is so vastly complex and difficult then how did the intelligent life on Earth form? If it's not that difficult given the vastness of the Universe why haven't we seen any other signs of life? I suggest, and doubt that anyone could show evidence otherwise, that the Earth is an anomaly in the Universe. Life exists only on this planet. This of course is a problem to the scientific community who would decry that this was all simply the work of evolution. If that were possible what would prevent it from happening elsewhere.I've often thought that cosmology was the bane of evolutionary thought as evolution falls flat on it's face once you leave the Earth. Imagine that this planet is the only known place in the Universe where evolution "happens". Can evolution happen on its own or not? Where then is the repeat of what happened on Earth? A great paradox for sure.
