Didnt we all evolve from the real Eve?

I watched a documentary on Eve, the first woman. Not biblical eve, because apparently she wasn’t the first, it was lillith(who was NOT a vampire). But my point is, why does this color divide exist? Doesn’t a rainbow coexist with every color imaginable in perfect harmony? Dont we all, humans, ooh and aah at their beauty? Well, isn’t it the same with people? This segregated world saddens me.
