Having watched the Mystery of the Sphinx, I must say I agree that for the most part, there is a high likelihood that the Sphinx could have been created long before we believe it to have been. The points raised by Dr. Robert Schoch are definitely very interesting and having seen his thoughts on other various monuments around the globe, it is unusual to see him take a viewpoint that actually backs up the statements of the archaeologists and other theorists, let alone actually fully support the theory from his own independent research. In most other theories, he is very skeptical about how realistic the ideas are and I think this strongly backs the case as presented. All in all, this is a very interesting documentary that, although may be a little far fetched towards the end, raises some very interesting points and I found myself glued to the screen for some time. I would highly recommend watching the Revelations of the Pyramids either before or after watching this as I feel this really helps to elaborate on the point and give alternative reasoning to the points that have been made here, as this shows that we don't actually know what the purpose of the Sphinx actually is for certain, nor do we have any real idea who built it. This is definitely one of the most astounding monuments that still exists on the face of our planet and I am very interested to see what future evidence reveals about the history of humanity itself. Overall I'd say that this is a very well thought out documentary, which tries to get across a point that really could use some extra thought and research by highly intellectual minds that are currently quite against the theory that humans could've been a civilized people for longer than we "know".
