One must announce a limit, when making such comparisons.
We are all from Africa, but we are also all primates, we are all from Greenland, at some point (if that's indeed where the oldest terrestrial tetrapods appear, but I'm just making an example)
This comes up often in racism/culture debates, whenever people argue who was there first, what was there first, they all got their own definition of "first", I mean, one can argue that Germans were the first to mass-migrate into Poland after 1939, granting them special rights in the territory :V
As a Scandinavian, I am particularily "sensitive" to the notion of Christianity "always" having existed in Europe. To most Europeans, Christianity goes back as far as most relevance dictate. Before Christianity is irrelevant-time of elves and Tolkien and Greeks and Romans doing their fairy-tale myth-stuff - as in, it's from "the before time" that we don't refer to anymore.
Scandinavians weren't fully christened untill the 1300s or so, there's no "always" about it, not even very far back, historically speaking
"We are all from Africa"
Actually that is being debated again. Its suspected that certain species of humans developed in the Americas BEFORE Asians crossed the land bridge. This happened separately from the eastern part of the world. Of course, its also being argued that the Asian settlers killed them/interbred with them all so it kind of becomes a moot point but the genetic material likely still exists in native-American and causoids.
It's not like "a rule" that we have to come from Africa, it's not to please black people, or anything, we go where the evidence goes, and so far, it's huge fucking mess
Humanity, as we know it, does come from Africa, even species of human developing in the Americas could not be human, if they did not evolve directly from the African hominins that gave rise to all the basal humans continously streaming out of Africa
Meaning - the American human species... came from Africa! At least their ancestors did, and that's the point. Norwegians never came "from Africa", but their ancestors did - as in, a quarter of a million years ago.
Then there is the further mess of more-than-one migration out of Africa, probably more like innumerable, as we're dealing with a continous stream, rather than a "hey ho, here we go!" type exodus
I love how complex and chaotic it is, but it is unfortunate in terms of politics, because here people prefer easy narratives
we go where the evidence goes, and so far, it's huge fucking mess
Oh, it especially is because the earlier hominids being discovered in the Americas are thought to have evolved separately than the African hominids. If enough evidence is found that is going to become a warzone of debate and identitypolitical fuckery. This is completely ignoring the side issue of ancient central americans having red/blonde hair and elongated skulls with different bone structure than normal.
Personally, I find it fascinating. You know full well it is eventually going to become "racist" though.
