“From what it seems they weren’t perfect: war enables innovation. The ancient indians didn’t war, so no innovations”
I guess it depends on which ‘indians’. American Indians, as far as I know spent much time on the warpath - but it didn’t get them much when Europeans arrived. As far as Asian Indians went - I don’t know enough either way.
Native Americans aren’t “Indians” - Colombus thought he reached India but was wrong.
