This is a significant finding, for what is underneath the Sphinx has been the food of much contemplation and prophecy. For example, Edgar Cayce spoke that something as monumental as the Akashic Records is contained therein. And the records and knowledge of Atlantis...
I had read that they had found what is underneath several years ago, and that the government of Egypt was not allowing foreigners access to it.
I have also read, or did I dream it, that finding the secret of what is contained there is a sign of the endtimes. I always thought that that was superstition at best, but then underwater evidence started turning up around Cuba, of the possible evidence of "Atlantis", right about the same time as 9/11.
In any case, I sure hope it doesn't turn out to be the case that, just as we unravel the mystery of our extensive ancient roots, we then blow ourselves up, and it becomes buried again for untold yugas.
