Of course. In the past, how did humans know what water was, what alcohol was, and kerosene? Humans only think that water is the cleanest because it looks so translucent.

If human beings see these alcohols and kerosene, they will not touch them, because their first impression is that they are oily, smelly, and unclean! It has been handed down in this way......

Since both alcohol and kerosene are too expensive, and the alcohol is too cold, kerosene has an unpleasant smell, and they are not easy to preserve. And water is everywhere, and it is colorless and odorless, and it is easy to preserve.

Of course, there are some things that can't be washed off with water, or if it's more difficult to wash, you have to add something else.

Because water is non-toxic. Colourless. Tasteless.
