You haven't disproved anything you tard. Are you actually suggesting nomadic hunter-gatherers never used cave shelters during winter and or blizzards and the only reason they ever did, is that bc according to experts 'they got lost from the hunting party and couldn't make it back home' Really ??.. Wahahaaa .... PS. You'll block me ??. Lol what an insecure faggot, just bc cause you entire premise reeks of appeal to authority and no-ones buying it. Fck you.
