Absurdity of Uniformitarians’ Timeline Highlighted by Supposed Antiquity of Walled City of Jericho 11,000 Years Ago?

Jericho, the first city taken by Joshua leading the Jews out of Egypt into the Promised Land, is said by the uniformitarians (biblephobes) to have been extant as a city with walls for eight thousand years leading up to that conquest by Israel, and they say its original inhabitants were some unknown people (see Wiki), yet the Bible tells us who built that city, the Canaanites, progeny of Canaan who was a grandson of Noah, during the Ice Age which followed Noah’s Flood.
