Well, let us be Aliens watching, waiting....biding our time....bruuuuuuhhahhsshshahaaaa. A'hem.
We see one branch of humans in Africa, were subject to constant invasion and enslavement, under the banners of various crazy "gods."
To StarView, the dark ones, were the beginning of the monkeys called Man, but because they never left the equatorial homelands they sat out the Ice Ages.
When the inner Age warming began these pitiful pale ones that survived, had become very mean and possessive and seeking conquest and slaves.
The Vikings are seen from SpaceView, as the beginning of the madness phase of "civilization". Scholars on the home world first believed the pale ones were deranged and could not prevail. But, later it was understood that the privations of the Cold, had expressed some very aggressive genes. It is still not settled as to why the pale ones have never allowed the darker one to have their own freedom much less their own countries until this Stardate -4 zios.
Studies will continue, in parallel, with the Vikings / Zulu simulations, local circa 1002 - 2742

....All in how we look at it. If we beat on all dogs, in general, is it any wonder all dogs look beaten on? And brother, these aren't dogs, but they have been beaten on, as sub-human, and never given a break. You are not looking at incompetency, you are looking at suppression, in every way, since the Flood.
