Egypt has invited the American businessman and founder of Tesla and SpaceX to view ancient structures. Eccentric billionaire Elon Musk recently tweeted that aliens must have built the pyramids. Egypt reacted as if stung by a wasp. Minister Rania al-Mashat of Investments and International Cooperation has now asked Musk to come and see for himself. "I admire your work and invite you to come together with SpaceX to investigate how the pyramids came about and also to go to the builders' tombs, we look forward to your arrival," said the minister. The world-famous Giza Pyramids near Cairo are the main tourist attraction of the country. They reopened in July, after a three-month shut down due to the coronavirus. The Egyptian pyramids were built as a tomb for pharaohs.
