Sphinx Lehner Position (~2500 BCE mainstream)
concept
The mainstream expert view dates the Sphinx to around 2500 BCE, and it's the credentialed baseline other theories argue against.
Who they are
Mark Lehner, an Egyptologist who founded and directs Ancient Egypt Research Associates.
What they do
The standard scholarly position that the Sphinx was built around 2500 BCE in the era of the pharaoh Khafre.
How it works
His dating fits the accepted Old Kingdom timeline and rests on peer-reviewed Egyptology and archaeological survey, giving it the highest source-reliability rating in the engine.
Why it matters
The engine treats this as the mainstream anchor point, noting that the rival Schoch and Reader datings are disagreements coming from qualified geologists inside the academy, not from cranks outside it.
