I brought up Luzia woman as supporting evidence to the Olmecs beings black. It wasn't to change the subject as you allege. The reality is the Olmecs only left those heads behind. By themselves your argument that they weren’t black might be valid. But once you add onto that the fact the earliest human remains in the Americas are that of a Black woman then we have more evidence to support the contention the Olmecs were black. Because if there were other black populations in the Americas then it makes the Olmecs being black more likely.

Whether they were from Africa or not is irrelevant. The key point is they LOOKED black. They had dark skin and "negroid" features. Just like how the people of Papau New Guinea have "negroid" features despite being genetically most closely related to East Asians.
One of your most consistent traits is trying to point out what others have "ignored" and absolving yourself of such scrutiny. You realize what you just posted is literally my last post's edit. I now invite you to actually read that article. Or if you're just feeling lazy peruse the blurb directly under the picture right at the top, especially the last sentence that ends in "wrong".
