That is your opinion. Both books are an unprovable theory, advanced to sell books. Both are interesting nonsense. That is my opinion. That’s all.
The book on the Dogon/Sirius B has already been shown to be nonsense.
JAW’s claim that the Sphinx is much older than the 4th Dynasty has already been examined by geologists (the best known being Robert Schoch) and found to be correct; much of the rest of the book falls into the usual imagineering of mystical symbolism. The Egyptians had their own magical thinking about the use of writing and carved idols, but I’ve never seen JAW claim that he could read hieroglyphic, hieratic, or demotic texts.
