No seriously, from Precambrian times (>540 million years) till Permian times (251 million years years ago) there were warn tropical shallow seas, including the neo-Tethys ocean, in the region now called Arabia, the shallow seas were part of the continental margins of the supercontinent Gondwana land.
Microscopic Plankton that lived in the shallow seas died and settled on the sea bed, and they were buried under several hundred to a few thousand feet of sediment. After a several million years the seas disappeared, due to Arabia colliding with Asia, and the correct heat and pressure underground cooked the plankton fossils and turned them into oil and gas. The oil and gas then became trapped underneath layers of Triassic shales and Permian Salt domes.
