I have this book and it is a fun read, but you have to keep in mind that most of it is high octane speculation if not downright disinformation. The example, the argument for monoatomic gold is weak at best and disinfo at worst.
In 1904, British archeologist Sir Flinders Petrie stumbled across a hidden temple on Mt Serabit called Serabit El Khadim in the middle of the Sinai desert. Inside the temple he found huge quantities of an unknown white powder that resembled ash yet strangely he found no evidence of the fires. Petrie assumed the powder to be ash from animal sacrifices but he himself admits there was no bone fragments what-so-ever or any evidence of sacrifice. He simply didn’t know what the white powder was.
My own research suggests that the powder was most likely sodium carbonate, derived from the dried lake beds of Wadi Natrun and the northern coast of Sinai. Here in this Serabit El Khadim complex of halls and shrines, there were numerous inscriptions relating to mfkzt, accompanying a variety of hieroglyphs for light. Also, in line with the Karnak reliefs, presentations of conical bread-cakes were apparent in the Serâbît wall carvings. One of these was a representation of Tuthmosis IV (MOSES?) in the presence of the goddess Hathor. Before him were two offering-stands topped with lotus flowers, and behind him a man bearing a conical object described as "white bread".
In the Old Testament book of Job states (28:5-6): “As for the earth, out of it cometh bread.” What is sodium carbonate or “baking soda” used for? Making bread rise.
Gardner has also suggested rather MANA FROM THE HEAVENS controversially that this is the very mountain in the Sinai desert under which the Hebrews, led by Moses out of Egypt, camped during the time of the exodus.
In the Biblical account, the name manna is said to derive from the question man hu, seemingly meaning "What is it?"; this is likely an Aramaic etymology, not a Hebrew one. Man is possibly cognate with the Arabic term man, meaning plant lice, with man hu thus meaning "this is plant lice", which fits the modern identification of manna, the crystallized honeydew of certain scale insects. In the environment of a desert, such honeydew rapidly dries due to evaporation of its water content, becoming a sticky solid, and later turning whitish, yellowish, or brownish; honeydew of this form is considered a delicacy in the Middle East, and is a good source of carbohydrates. In particular, there is a scale insect that feeds on tamarisk, the Tamarisk manna scale (Trabutina mannipara), which is often considered to be the prime candidate for biblical manna. Its important to note that the sugar mannose and its hydrogenated sugar alcohol, mannitol, are derived from the word manna.
