Do I believe other sapient species exist out there in the universe? Yes. Do I believe they have interstellar travel and have visited Earth? I’m doubtful.
yeah. I think the same logical consideration of the odds that would lead one to believe that other life probably exists, somewhere, would also lead you to believe that it is so staggeringly unlikely that we will ever meet it.
but who knows, humans are always learning that they were wrong about the things they used to be so ignorantly sure of.
