I'd imagine those coming from Africa and Europe (if they did) were in small sporadic pockets.
I'm just wondering, if people did come from Africa they would have taken the west coast, to Caribbean sailing passage, but the oldest settlements in South and Central America are far south.
Europe was probably through glacial hopping.

I have no doubt that we have been lied to about a lot of history.
l'm not so sure when it is pure ice with no land.
What Happened to All of Them? The Mammoth Steppe ecosystem vanished at the end of the Pleistocene. Some experts argue that humans are responsible for the megafaunal extinctions (Alroy 2001), but across Beringia, we know that humans co-existed with the extinct species for long periods. Documented 14C dates show that humans in Alaska overlapped with horse, bison, and lions for >1,000 years and also probably with mammoths, and we lack evidence of overhunting of these animals (Mann et al. 2013). The region of Beringia is vast and the early human population was small. A more likely explanation for the extinctions is that the prolonged warming at the end of the Pleistocene caused environmental changes that did not favor the Mammoth Steppe megafauna.
Pleistocene Megafauna in Beringia
Although it's gone now, the Bering Land Bridge persisted for thousands of years, from about 30,000 years ago to 16,000 years ago, according to global sea level estimates, said Julie Brigham-Grette, a professor and department head of geosciences at the University of Massachusetts-Amherst. Brigham-Grette, who advised Bond on sea levels and geography, was one of the many scientists who offered helpful information to Bond during the making of the map.
Humans Crossed the Bering Land Bridge to People the Americas. Here’s What It Looked Like 18,000 Years Ago.
Even though some additional minor founder types have been later identified in North America, such as X, the hypothesis of just four major founder types in the initial colonization of the New World remains uncontested. However, the timing of their entry remains debated. Previous studies of mtDNA data place estimates for the peopling of the New World in a broad range from 11,000 to over 40,000 years before present (ybp) [reviewed by 20], although more recent estimates range from 20,000–15,000 ybp [21]. Recent archaeological evidence places Homo sapiens in northeastern Siberia at the Yana Rhinoceros Horn Site as early as 30,000 ybp [22] about twice the 15,000 ybp [23] date for humans at the southern end of South America. These archaeological dates suggest two likely scenarios. First, the ancestors of Native Americans peopled Beringia before the Last Glacial Maximum, but remained locally isolated (likely due to ecological barriers) until entering the Americas at 15,000 ybp (Beringian incubation model, BIM) [24]. Second, the ancestors of Native Americans did not reach Beringia until just before 15,000 ybp, and then moved continuously on into the Americas, being recently derived from a larger parent Asian population (direct colonization model, DCM)

One time I was rendering a 3d model of King Tut and I couldn't shake how Asian his sarcophagus' face looked.

there is evidence that Beringia/ Bearing Land Bridge wasn't completely covered in ice and had a fairly dry climate and one DNA study suggests that there was a stand still period where people actually lived there for a period due to being blocked in by ice on both ends, my words.
there is fossil evidence of vegetation, animal life, and humans.
Hancock doesn't have any ideas. He's a journalist. He simply makes money by popularising other people's ideas - and then moving on to another, when the first falls out of fashion ...... Which is why he's long forgotten all about Atlantis in Antarctica and SE Asian temples replicating the patterns of European constellations.
