Yet that proves nothing. I’d point out that the fact there are multiple planets around our own star and the theory of how the universe evolved predicted planets around other stars with near certainty, and we even had an idea of how to detect them it was just a matter of a sensitive enough instrument and computational techniques. We have nothing equivalent for life. But not for trying, we absolutely have, quite a lot with many techniques. But yet, nothing. We don’t even have a theory for how life emerges that’s very advanced or verifiable. I’m not saying we are alone. But the fact we exist doesn’t prove other life exists, and it doesn’t mean life is plentiful. If there were one person left on earth, they would observe a planet and assume there must be more people because how could they possibly be alone? Yet, by construction, they are. That incredulity doesn’t change anything. I’m not asserting we are alone, and I believe we aren’t. But just pointing out our belief proves absolutely nothing, and holding the opposite belief doesn’t mean egotism. It’s actually the most rational belief given all evidence that we are alone.
