By that reasoning, one would conclude that people today don't have any spiritual needs. And yet the humans of today seem to disagree with that view in large numbers. The humans of 100 years ago disagreed in far greater numbers.
So... are they all mistaken about what they need? Or is there some line somewhere between humans of 100k years ago and those of today? Or is it after all reasonable that humans of 100k years ago might have had spiritual needs?
That's an odd conclusion to draw. My point is there is clearly a line at some point in history, and nobody knows when it is. But it seems that spirituality would require at least spoken language, can we not agree on that? I don't know what the consensus is on when spoken language arose. I'm assuming it was not close to 100k years ago.
