The Great Pyramids of Giza were built in 2550 B.C. Cleopatra was born in 70 B.C. And the first moon landing took place in 1969. That means that there were approximately 2480 years between the building of the Pyramids and the birth of Cleopatra, but only 2040 years between the birth of Cleopatra and the first moon landing. You can argue all you want, but this will remain true no matter what you do. Even a thousand years from now, people can use this fact to astound their friends and family (if of course, people still exist then. And they know about Cleopatra and the Pyramids.)
