I don't understand either. Personally, I believe the rare earth hypothesis is more credible than it seems at first glance. But the matter is warped by our own definition of life, in that we're looking for familiar things (i.e. humanoids or bacteria or radio signals) out there. For me, when looking deeply at viruses, kinesin or even something like fire, the line between living and unliving seems like a pretty arbitrary definition in many ways. Which is fine, but if we decide the definition is something resembling us, or life on earth, then I think the rare earth hypothesis seems as credible as any other theory. Not to mention when you think deeply about physics, or just how inhospitable the vast majority of space seems to us. But on the other hand, I guess finding anything extraordinary or complex is all that we're really looking for. But, regardless, I guess I am just confused, as bothersome to me sounds a bit like worry. I am not worried (i.e. bothered) about the matter, as it seems irrelevant to my livelihood. I believe I will die without knowing either way and have no qualms about that. But if you are bothered by the matter in the sense that you're just very interested, curious, and desiring to know, that's very understandable. It would be truly awesome if we found concrete evidence of life elsewhere.
