Fact is mankind is an animal specie divided into races, just like in any other animal specie.
These races fight each others indefinitely and randomly for limited resources. Sometimes a race inside the specie will eradicate, genocide another race or all others races. Sometimes there are mutations, "mixing" between races and new stronger, more adapted races appear.
All races in the human specie will keep fighting each others for resources , there will be mixing, mutations, but ultimately only the richest, strongest, will survive, and probably, become "gods" able to reverse engineer life and re-create it somewhere else in space before the sun goes boom.
Or we ll all disapear due to a man made or natural cataclysm or illness.
History teaches us the past is all about wars, so is the present, and so will be the future. Life is war, at all levels. And the weakest, unfit, unable to adapt, disapear and not a single fuck is given because that's just the rule of the "game".
