This is well know, how most of North Africa extending into Spain and the Middle East became desertified in relatively recent history largely through deforestation and disruption of the water table.
Oglesby suspects that deforestation contributed to a drought. Lake sediment cores indicate that the Mayan deforestation appears to have coincided with natural climate variability that was already producing a drought. “Combined with the land-use changes, the drought was a double whammy,” he said. By 950 A.D., the Mayan lowland cities were largely deserted.

The Middle East did not become "desertified in relatively recent history"..... Fist of all, the lands that were bought by Israeli settlers from Palestinians WAS A DESERT, and only through modernization was the land of Israel and surrounded areas become more hospitable, which is why the Palestinian authorities in part want Israel back now, because the Israelis made it into an oasis.
Second of all, it was mostly parts of the Nile which was green, and fertile, it wans't the entire Middle East as most of the Middle East has been a desert for thousands of years, not to mention that this happened to the Nile at least 10,000 years ago....it didn't just happen now....
There are still some parts throughout the Nile that are fertile, and green.

(2) They became so advanced and mastered the time of space that aliens acknowledged this and took them to another planet. afterall there are buildings in shapes of mayan symbols placed on mars, right? this makes perfect sense. They progressed and were promoted to a new world.
