Funny response and probably true to some extent although all human groups seem to have archaic hominid admixture whether it's neanderthal, denisovan or "ghost" dna (Why did they choose that name?). I think ultimately, controversy by controversy, the academic community will gradually admit that 'humanity' has a much longer "pre"history than we like to admit. Likely on the order of 1-2 million years. If I had to bet, within the next century some archeological evidence will be unearthed that shows some level of Civilization (tm) among humans that lived over 100 kya.

This has to be (roughly) true because the energy to power the size of brain found in hominids post 2Mya can only come from cooked food (or living in the very small number of places where there's enough fruit available year round to provide equivalent diet).

Huh? The academic community has been clear on that for decades now. The problem is the oversimplification taught in schools, which is often decades behind the cutting edge science. See the timeline on the archaic humans wiki page [1]. The first migration out of Africa and the first use of fire were all millions of years ago. The first stone tools made by Australopithecus predate archaic humans altogether. It really just depends on where you draw the "human" and "civilization" lines.

Indeed, something along those lines was announced just the day before yesterday: "Waterlogged deposits at the archaeological site of Kalambo Falls, Zambia, dated by luminescence to at least 476 ± 23 kyr ago (ka), preserved two interlocking logs joined transversely by an intentionally cut notch.
