<The cave drawings in Europe show how much importance these people placed on the hunt.

No - the cave drawings are indicative of how important preparatory ritual was to the hunters; not the same thing.

I find myself in the awkward position of recommending an absolutley awful book, The Shelters of Stone, the latest in the absolutely awful "Earth's Children" series by Jean Auel. (Never mind why I've read the whole series... I have a perverse weakness for trash fiction.) The reason for the recommendation: no matter how execrable a writer, one cannot fault Ms. Auel for lack of research. Survival in periglacial Europe required a far more complex society, including economy and diet, than your simplistic carnivorous assumption.

By the same light, the lack of similar art in other regions of the world - some of which have been "peopled" for tens of thousand of years longer than Europe - does not in itself indicate a difference in diet, let alone a difference in basic intelligence in the people who lived there (and still do). The survival of cave paintings is due to the efficacy of stone caves in preserving organic materials; in more temperate climates where shelter is less necessary, artifacts are free to 'biodegrade'.

Your pathetic, transparent attempts to justify 'white supremacy' on pseudoscientific grounds have been noted. However, as someone said to me earlier this morning (in another context), "the First is the First"... by which she meant the First Amendment. Fortunately for the rest of us, your talents of persuasion are as lacking as your ignorance is not.
