Egypt has invited billionaire Elon Musk to come and visit its pyramids — after he tweeted a conspiracy theory that aliens built the landmarks.
“Aliens built the pyramids obv,” the SpaceX and Tesla boss, known for both controversial and tongue-in-cheek Twitter posts, wrote Friday.
Egypt’s Minister of International Co-operation Rania al-Mashat replied to the CEO’s tweet the next day.
“I follow your work with a lot of admiration,” al-Mashat wrote. “I invite you & Space X to explore the writings about how the pyramids were built and also to check out the tombs of the pyramid builders. Mr. Musk, we are waiting for you.”
Egyptian archaeologist Zahi Hawass’ criticism took a harsher tone, calling Musk’s statement a “complete hallucination.”
“I found the tombs of the pyramids’ builders that tell everyone that the builders of the pyramids are Egyptians and they were not slaves,” he said in a video posted to Facebook.
Hours after the initial post, however, Musk tweeted a BBC History article about the lives of the pyramid builders.
“This BBC article provides a sensible summary for how it was done,” he wrote.
Egypt has more than 100 surviving pyramids today — and the Great Pyramid of Giza, standing at more than 450 feet, is the most well-known, according to the BBC. Most were built as tombs for Egypt’s royalty.
