What if the stars around us are of Sentient life devoid ? Binary stars and Giant blues are common in the void. Binaries do not provide a habitable clime Blue Giant Stars burn fast and short- Evolution needs more time. Giant Reds live long enough but keep few planets warm. Perhaps upon a distant rock there is some primal goo but that is quite a ways away from beings like me and you. So please be better stewards of this third rock from the sun That lovely little yellow dwarf round which our race is run.
