Pyramid Stone With Faces, Figures and Vertical Cut Marks

This stone features a number of obvious faces. It also includes a series of vertical cut marks and what seems to be a deliberate charred spot. From one angle, it looks a bit like a pyramid. The last seven photos appear to depict some kind of scene. On the left side of the stone is a face and within that face what looks like a hooded ET-like figure; to the right is a smaller figure, the charred spot and a Sphinx-like character. Although I can't decipher its meaning, it feels as if this stone is telling some kind of story.
