They claim that it will float (specific gravity < 1).

From archaeological work, we know that the pyramids at Giza and the famous sphinx, are not 12 000 years old. There's much, much more evidence for them having been built during the Egyptian Old Kingdom, around 4 500 years ago. In any event, the uncertainty is closer to 100 years, than to 10 000.
Here's the background behind the 12 000 year theory—which is regarded as lacking credibility.
