If you’re interested, here’s a video I posted recently (along with some comments) about hypotheses related to the origin of life, the probability thereof, and therefore the likelihood of alien life even if conditions are optimal. In fact the whole thread is a pretty good read. The formation of life from inorganic chemicals, a process called abiogenesis, might possibly involve some extremely improbable processes that just happened to occur here by sheer accident. I personally don’t believe that, but it’s one of the hypotheses that’s been proposed to explain the Fermi paradox.
It only feels good if you’re predisposed that way. But not everyone is, or we wouldn’t have evil in the world. Some people are just selfish, others indifferent to the plight of others, and some are actually motivated by cruelty, being marginal or perhaps all-out sociopaths.
