Do you have any evidence that all sides of the debate agree on these five points?
I agree with No 2 that the Sphinx is in Egypt. I don't know enough about geology to comment on its condition as per No 5.
Having read most of the postings on this site over the last 2 months, I beg to differ that there is consensus on your other three points.
As to No 1, a lion with a man's head, there was discussion some weeks ago as to the possibility it is Annubis; more like a dog. Personally, I take the view that the Sphinx is a symbolic creature; mammalian paws [slightly exaggerated] attached to a serpent/reptilian type of body and who knows what the head once was?
As to Nos 3 & 4; 'the Sphinx was carved by Human beings'. I neither agree nor disagree as I don't know. The only thing I will agree to is that nobody knows. Refer yesterdays thread "Physical Interaction with Spirits" and the discussion on the Nephilim: perhaps they built it with their supernatural powers? Just before Christmas there was a discussion as to the possibility of Interdimensional beings having provided the knowledge upon which the Ancient Egyptian and Dogon languages are based. Perhaps these Interdimensional beings created the sphinx using what we refer to as supernatural powers but which are normal powers to them?
