An "oasis" (singular) is generally an isolated fertile place usually far from any other water sources in the middle of the desert or in remote rugged, arid regions.
The water in the oasis comes from underground aquifers that rise to the surface or from small or underground streams that flow into a broad basin making a deep pool.
Travelers from times ancient upto 200 years ago (bedouin) saw these places as sacred because they were in essence "islands" of life in the middle wilderness without which, they and/or the animals would die.
Oasis usually had date palms and in a lot of cases some locals would cultivate fruits in them. Melons and cucumbers were prized and rare as they require so much water to grow their fruits.
Oasis were frequently nuetral places also. tribes in conflict with each other would observe a truce at these place which would last for one days journey away from the oasis.
Ancient Egyptians did not really need or use oasis unless on a war campaign in someone else's country as Egypt (in ancient times) was nothing like it is today. It was green, marshy and very wet and fertile. The annual flooding of the nile brought tons of water and nutrient rich soil which the Egyptians were very clever at trapping.
