We are more alike than different. The atoms in our bodies are the same forged in distant stars; Carl Sagan said we are "made of star stuff."
Then: we evolve under ultraviolet light at degree inclinations on the globe, thereby changing the prominence of Melanin in our epidurals. Due to war and conquests, we craft a narrative of what is godly, who is "divine" and who is deviant. Good and evil has a hue or light and darkness. And thus, we craft the seeds of our own self-destruction from ignorance, hubris, racism, snobbery and xenophobia.
Star stuff should be better behaved.
