The science behind it is just god damn confusing. How the hell did something that evolved on another planet thousands of light years away be a closer relation to humans than even chimps?
When the aliens came, they came looking like us. They came with gifts and knowledge, but as y’all know nothing in this world, or universe, is free.
They brought gifts, but they wanted something else in return.
Our blood. Their food. God damn Space Vampires.
And our leaders told us to bleed and smile. And we did. And we took to the stars and never looked back.
