They were not all speaking the same language
https://faculty.gordon.edu/hu/bi/ted_hi ... el_wtj.htm"At numerous sites in North America, such as Danger Cave in Utah, stratified
remains of Indian cultures are radiocarbon-dated from 9000 to 3000
B.C.64 At Sierra Madre Oriental and other sites in Mexico, human and cultural
remains are carbon-dated from 7000 to 1400 B.C.65 Since these Indians
apparently came from Asia originally, we would expect their languages around
5000 B.C. to relate to Asian languages, but not to ancient Near Eastern languages.
In any case, whatever languages they may have spoken, they were in America
speaking them before the tower of Babel began to be built and, all during the time
from 3500 to 2000 B.C.
We can say then that there is firm archaeological ground based both on
radiocarbon dates and stratified sites to support the conclusion that long before
the tower of Babel began to be built and all during the fourth millennium B.C.,
men were scattered over the entire globe speaking a multitude of different lan-
guages. This conclusion is clearly opposed to the assumptions underlying
Gen 11:1-9 and opposite to the statements in 11:1 and 6 in particular.
At this point someone might suggest that perhaps the tower of Babel should
be dated earlier. But, on what basis would anyone suppose that it should be
dated earlier than c. 3500 B.C.? "
