    It’s not “fairly widely accepted”. The Fermi Paradox is based on the Drake Equation, which has a long chain of assumptions about how rare it is for life to form and grow. Life can easily be a one-off in general, since we don’t have good ranges for those measurements.

    Our planet is perfect for life to form and, as far as we know, it only happened once here in billions of years.

      Given how life started on earth almost immediately after it cooled down it is fairly widely accepted that there’s life out there. What level of complexity is up for debate. Also, if the universe is infinite and the laws of physics are the same everywhere, there is a 100% chance that there is an infinite number of exact replicas of earth and its history out there.

        It’s not “fairly widely accepted” because there’s literally no evidence for it. Anything can happen once. Something happening once is not evidence of how common it is. For that, you need to count how often it happens. We have only the vaguest ideas about how common certain requirements are, and less information about potential hurdles.

        That’s the point of the Fermi Paradox: if the Drake Equation estimates are right, we should see life everywhere in the universe. The fact that we see no life indicates that our assumptions are wrong.

          It is incredibly arrogant to think that in something as unfathomably large as our the universe that humans are the only form of life.

          Whether other life forms are advanced enough to be detected by us or even for space travel is an entirely different matter.
