Thanks.
And Respect: I am not stepping on your wife's people, or their story...
I never took it that way, so no offense taken.
When someone looks at some of the goods found at Cahokia or some of the Hopewell communities, trade goods from all over the continent were found, from the gulf and west coasts, the UP of Michigan, the Carolinas, you know people traveled extensively. I think the amount of travel and the ingenuity involved has always been underestimated due to a Darwinian tendency to see 'our' culture as the pinnacle, and 'their' culture as less developed, which fits with the linearity in Darwinism, and justifies the Colonial 'guidance' used to exploit or loot entire civilizations. The preeminent logic has been "That can't be ancient Hebrew carved on those rocks in AZ, because there weren't any ancient Hebrews there, or the Norse weren't in Minnesota (well, not until the 1800s), or the Phoenicians in New England, so evidence will be ignored, because, well, "They weren't there, it couldn't have been them". What writings that did exist that were not destroyed, were mostly carved in stone (literally), the rest were burned as heresy even though the ones feeding the fire couldn't read them. I'm a bit of a heretic as an archaeologist, and far from the only one, and only now is that beginning to gain ground and let the evidence (once carefully verified to not be some elaborate hoax) do the talking.
People have done amazing things. People have crossed oceans on rafts, in rowboats, and reed boats, in the last 100 years, what's to keep them from doing it then?
