I have family from all over the world, including a white Grandmother born in India from white English parents, she then moved to South Africa where she had my mother, who immigrated to Australia where she had me.
I can’t think of a logical reason a DNA test would actually reveal that-
I’m under the impression that this is just a glorified melanin gene tracker? How would a DNA test be able to determine ancestry at all, considering that we kinda just put lines on a map and said that made them unique? How does the dirt around you effect the dna in a traceable way? And if they can’t, what do they actually do and what’s the point of them?

The test tracks specific mutations that are most common in certain areas.
For example one gene is mostly found in central europe, if you have that gene at least a part of your heritage is likely to stem from that population. (The mutation happened there, and spread locally but hasn’t reached other populations in a large quantity yet)
It can’t track where your family was, it can only track where the source material came from, and that only with a limited precision. The percentage values are pretty much guessed.
If your family is entirely european, moved to all around the world but never married any locals then it would say 100% european most likely. (Though people intermixed a lot, so that scenario is very unlikely)
>considering that we kinda just put lines on a map and said that made them unique?
In the past people moved much less than today. The genetic exchange between for example europe and east asia was pretty close to zero before colonization. The test can’t reliably tell you if your family was in france or germany, but it can tell you if it was in france or japan.
