Given the abundant presence of oil, which is generally thought to come from the fossils of plants and/or tiny marine organisms, the area must once have been densely forested - and that for a very long period of time. But that was at least some 100,000 and probably millions of years ago. Then the climate must have changed to arid and hot, killing the vegetation. And since it was the vegetation that through its roots kept together the good top soil, its dying off caused the fertile soil to be blown away, leaving only sand. The total absence of rivers on the Arab peninsula (apart from a few near the coast) also contributed to the area's dryness.
Why the climate very long ago changed to today's very hot and dry conditions we don't know. Some scientist think that the Arab peninsula breaking loose from the African continent millions of years ago may have had something to do with it.
