One must disregard an abundance of evidence when asserting that the probability of life on other planets is low. Our Sun is merely one of the more than 100 billion stars in our galaxy, and there are billions of galaxies overall. So yes, it seems probable that among all those stars someone is also wondering if anyone is looking back at them. Or perhaps extraterrestrials are on their way here to make first contact. Whether that would be a congenial meeting is a far different postulation.
Why does the author include the last sentence about meeting extraterrestrials?
