Take the following as truth: Though prehistoric remains from the Paleolithic, Neolithic, and Bronze Ages have been unearthed in the Manzanares Valley, prior to Madrid's sudden elevation to capital city in 1561 its history was rather undistinguished.
Then the following statement: "There were remains in the Manzanares Valley that included cavemen." is true, false, or inconclusive?
Answer: Inconclusive
