The pyramids were underwater

I love thinking about the pyramids and how they were built (and by whom). Nobody actually knows. And I absolutely don't believe the mainstream narrative.

Roger Cunningham, AKA the The Ethical Skeptic, has been researching this for a long time, and makes the following arguments:

• the established timeline is wrong by thousands of years;
• they were built by advanced people;
• the truth is being covered up; and
• the pyramids ended up underwater for centuries, following a cataclysmic event.

How can you not find that fascinating?
