There are currently about 7 billion people on the planet, all of which require water to survive. Even without the direct consumption of water, water is usually in most other beverages that people consume. Also, many of these billions of humans use massive amounts of water everyday to do laundry, bathe, wash dishes, and so forth. Many animals require water to survive as well.
Also, humans and animals requiring frequent water consumption has been a thing for billions of years. Obviosuly Earth’s water supply is not infinite. How have we not already exhausted all the water the Earth has to offer?

when you use water, you don’t make it ‘not water’. think of all the things you do with water.
you drink it, but at same time, you sweat it and you pee it. 1 water goes in, 1 water comes out.
you wash your clothes and dishes with it. 1 water goes in, 1 water comes out.
the big one that makes water into not water is growing plants/crops. plants take CO2 and water and split it apart in photosynthesis to make glucose (sugar) and oxygen and a little water out. 2 waters in, 1 water out. it’s a good thing that when we digest crops as food sugars, we take 1 glucose and oxygen and get CO2 and water and energy as output. completing the cycle
