The New Age view is just as wrong as the ancient aliens view. They have a conclusion before they have facts, then put the facts in order to support a conclusion. If you look for it, you will find it. Even though it may be viable, they have to search really hard sometimes to get you to believe some stuff, like the idea that massive stones can be made to levitate in order to construct monolithic structures like pyramids (literal translation is indeed 'fire in the middle'). It is good to be open minded, but going too far and looking for evidence of magic is just crazy. It does make for good entertainment though.
Even Robert Schoch admits Yonaguni is natural. However, there is no doubt about the ruins off the coast of India, they are antediluvian and advanced, complete with writing that predates cuneiform, and it is the "scientific community" in the west that is most vigorously blocking honest investigation.
That being said, I think Graham Hancock is on the right track in his search for a lost civilization. I think that John Major Jenkins has a better understanding of Mayan cosmology than any Brigham Young scholar. I think that if a great advanced civilization such as our own were to face cataclysm, within a half precession cycle, the only remnants would be the monoliths, so who is really to say that Plato could not be taken for his word about Atlantis?
As for Egypt, well you have two opposing camps, one that was led by the late John Anthony West and the other led by Zahi Hawass. Both of these camps have an agenda. Zahi Hawass wishes to keep Egypt for the nationalist pride of an Arab nation that is relatively new in the area. John Anthony West believed in magic.
Just let honest inquiry commence such that sound conclusions can be drawn. I think that science (not New Age doctrine and not nationalist Egyptian goals) will likely discover that there is indeed a missing chapter in human history. It would be careless to take this as proof of the rest of the outlandish claims within New Age doctrine.
Madonna and child symbolism is very common in Mesoamerican iconography.

This is Olmec.
If you had already decided on a conclusion, this would appear to be evidence of an early connection between two foundational civilizations, if you had a clear mind when finding this, you would only see that such a theme comes from deep within the human psyche.
