Way more convincing is the indisputable geomorphological evidence.

The pyramids are from the same era as the Great Sphinx.

Sand erosion causes lateral scratching of rock whilst rain water causes vertical erosion of rock.

By a massive margin the dominant erosion on the Great Sphinx is VERTICAL ROCK erosion. This would indicate that it dates from shortly after or at about the same time as the end of the last Ice Age, when the region was a dense Amazon-style rainforest, being pelted daily by savage thunderstorms, at about 12,000 BC, ( 9,200BC being actually probably too recent(.

After about 7,000 BC it would have been utterly impossible to have had any degree of vertical striation, let alone the dominant.
