... yet some speculate we humans might be somehow unique and alone in this universe because we haven't yet met any space aliens like us.

If we can't see that spark of sentience and intelligence in our own immediate neighbors, how the hell would we recognize it in space aliens?

Maybe that's why space aliens avoid this place.

I've known many amazingly bright dogs and birds, even a few cats, and I love to watch videos of elephants, horses, and cetaceans who are clearly thoughtful and playful creatures who celebrate life.

It makes me sad there are humans who won't even respect the individuality of fellow humans beyond their own small tribes, and in the worst cases of sociopathy and narcissism, beyond their own selves.
