The Pyramids of Giza pre-dates Abraham by more than 1000 years. The ancient civilization was quite advanced for its time. As we can see from this mural in the lower right corner they used computers even in that day. Wait! It must be a hoax. Nobody uses Cathode Ray Tubes anymore, and they certainly didn’t then.
In best socialist tradition the High Aswan Dam was completed in 1970, regulating the flow of the Nile River, creating Lake Nasser and producing electricity. It looked good on paper and wa a worthwhile project unless you count for the unintended consequences.
A large number of ancient monument had to be removed from the future lake-bed or they would be destroyed. Egypt was not going to save the relics of the old civilization, so the rest of the world had to pay for their move. Only the most famous were saved, the rest are in the process of being destroyed.
The evaporation in lake Nasser, being in the desert, water evaporates at a rate of between 0.15 and 0.4 inches per day, so 25% of the water of the Nile is not flowing downstream, reducing the electricity production. In addition, the silt that used to fertilize the lower Nile and the Nile Delta gets stuck in the lake.
This has caused the Mediterranean Sea fishermen to lose 90% of a previously lucrative shrimp harvest. On the plus side the fish catch in Lake Nasser is increased. The silt that used to fertilize the Delta has been replaced by fertilizer, which is very expensive. On the plus side water is regulated, and the Delta never floods, so they can grow more harvests, even during the low water season. On the negative side, since the canals are always filled and never drying out, the canals stink and are filled with leeches and disease causing bacteria, viruses, amoebas and all kinds of pollution.,
