There could be some sense figuring first out water containers. Old saying is that human survives few minutes without oxygen, few days without water and few weeks without food. Water > Food

Also as a hunter gatherer, food is around you (berries, roots, game) and you can carry them with you. Drinking water is more scarce and keeping it with you when you move around needs some container.

You mean C#, the Microsoft Java.
