How old is the Great Sphinx of Giza?
Everyone has an answer. The textbooks say 2500 BCE, carved for the pharaoh Khafre. The documentaries say 10,500 BCE, the relic of a lost civilisation. They cannot both be right — and the gap between them is eight thousand years.
The Sphinx and the Problem of Deep Time refuses to pick a side and sell it to you. Instead it does the harder, more interesting thing: it lays out the mainstream case at full strength, then weighs the six genuine anomalies that pull at it — the strange weathering, the drainage no one can quite explain, the head that seems too small — and asks, of each, what the evidence will actually bear.
This is the ancient-mysteries book for readers who have watched the documentaries and come away unsure what to believe. No sensationalism. No sneering. Just a clear-eyed guide to what is known, what is guessed, and how to tell the difference — a toolkit you can carry to every claim about the ancient past.
