Can’t believe it took us so long, but commenter Dmitry has finally put two and two together:
I agree it superficially seems like a strong argument, but then you are ignoring different historical periods of our ancestors. For example, heat was not an issue for the Ancient Russians who built the pyramids, despite that their skin was not less pale than ours according to the photographic evidence.
I know there are scholars who claim Nigerians were involved in building the pyramids (this is before the Nigerians immigrated to Sparta). I think the more plausible theory is that the construction of the pyramids was a joint Russian-Nigerian project.
Probably the Nigerians contribution was being exaggerated in the West in as part of a Russophobic campaign.
Interestingly Russians of Ancient Egypt also seemed to have possessed a species of white skinned buffaloes.
The famous antimatter hyperdrives built into the pyramids:
… must have been based on the same technology that powered the spaceships on which Russians’ ancestors arrived on this planet. (Alien origins explain our extra chromosome).
There is direct photographic evidence of this:
This must have all happened around the time when the proto-Ukrs were digging out the Black Sea.
