Life on Earth could be the weirdest form of life in the Universe.

We could literally be the weirdest form of life in the universe and we would never know. After all, the only knowledge we have of life is on Earth. We could literally be weird in everything, maybe life is not supposed to feel love, emotions. Maybe Life doesn't conduct violence. We could literally be an irregular. A failed product. A form of life that is broken, like a glitched computer, a form of life that doesn't work correctly. An outlier from all other existing forms of life in distant planets or galaxies. Yet we can never know.
