Even the uniformitarians agree that northern France has no ancient human history until circa 1400 b. c., actually because that’s when the Ice Age ended, which freed-up that land which had been covered by snowpack, when soon after, Brutus a great grandson of Aeneus of Troy founded Troyes and Paris on the Seine river and Tours on the Loire, also into the British Isles, a large peninsula of Western Europe during the Ice Age (when the sea level was a few hundred feet lower) with snowpack on the interior.
