It means that Cleopatra's lifetime (69-30 BC) was closer to the Moon Landing in 1969 than the construction of the pyramids (I assume they meant the Great Pyramids of Giza, which were constructed around 2500 BC), despite the fact that Cleopatra is also associated with Egyptian culture and history. Therefore, Cleopatra lived around 2000 years before the moon landing, but 2500 years after the construction of the Pyramids. So, she lived closer in time relative to the Apollo 11 moon landing than the Pyramids.
