The first civilization was somewhere in Sumer no more than what? 7000 years ago? Youre more than doubling, scaling back the inception and retrofitting of a people and identity that simply didnt exist at the time into a territoy that had yet to have a history of its own. Youre simply talking nonsense. Your following questions are just as inept.
I have no idea what you're trying to say. It doesn't have to be a city-state, hunter gatherers have been making tools, making cave art, leaving behind their bones, etc. for hundreds of thousands of years. There's no evidence of any of this in the Americas before the Siberians went over, no ancient human presence at all like we see in Africa, Europe, and Asia.
How can you claim that aboriginal americans existed before the siberians came over and yet left no trace of their bones, tools, homes, anything?
The self depicted murals depict a non mongolid people, mongoloids will never have black skin unless they are admixed, this mixture is commonly found in SEA Asia which, again, still possesses remants of its aborginal population that allows this genetic mixture to occur. Do you understand how this carries over into the americas as the non existance of a pre-native population would preclude this from happening.
First off "mongoloid" is an old-school racist category with no scientific basis at all. Claiming "mogoloids will never have black skin unless they are admixed" is just a made-up statement. As I already pointed out, aboriginal southeast asians have their own genetic structure separate from east asians, but they're still more closely related to the east asians than to any other group. They are not related to aboriginal africans or native americans at all.
How often are the black native of asia spoken about?
Youre fixated on irreverent bullshyt to force your narrative. When a philpinno takes a genetic test does it account for this black native population? No, despite it being apart of them, a biased foundation that fails to thoroughly examine these transient, both easily and largely dimissed criteria.
They're talked about plenty if you move in any realm where this shyt is actually discussed. You can read the studies on it, it's just a lie to claim it's not accounted for.

To your last question, ask the same about the native black asians, how did it occur? Despite it occuring however, as it surely did, these people still exist to dismiss your disbelief in forcing these shallow rhetoical questions
There's no doubt on how it occurred. Hunter-gatherer groups of aboriginal southeast asians hadd their home territories invaded by east asians, they were oppressed, attacked, enslaved, etc. over history but still maintained their groups to a degree. This a long record of this.
That's nothing like you're trying to claim for the Americas, where you're making up an imagined very recent conflict between aboriginal americans and invading siberians that you have zero evidence for, somehow insisting that the aboriginal americans were dominating the culture and places like the Mayan Empire up until recent history, but then suddenly disappeared and now all these siberian-original native americans are magically filling up the region speaking mayan languages and speaking of their mayan past without any trace of your hypothetical aboriginal american DNA.
You seem to base most your arguments on assumed ignorance, excusing your lack of evidence by just waving your hands around and claiming we can't know anything while still insisting that you know everything.
