Ancient history: the stone facts, the dates, and both sides of the debate
We test the biggest claims about the deep human past, from water-worn grooves on the Great Sphinx to laser-mapped towns under the Amazon trees. Every page keeps what is measured on site separate from what people think it means. We link every source paper and label each claim Mainstream, Contested, or Leading Edge.
Our method: we start with plain English and hard numbers first. We give both mainstream scholars and Leading Edge writers a fair hearing, and we share our check code openly. How our labels work →
