Why is water left out of calculating Ka?

I think water is considered to be a constant in the equilibrium constant formula (it is considered to be 1) because it shouldn't affect the equilibrium of the reactants.

I believe Ka only focuses on the formation of acids (i.e. HCl -> Cl- + H+) so thus water won't really apply here.

Water is considered to be neutral because it is neither an acid or a base, so it does not affect reactions of acids and bases. Rather, the acids and bases affect the water

Water is left out of calculating Ka because it is neutral. Therefore, it doesn't really affect anything in the formula, and doesn't change anything if it's left out

Water is constant so it doesn't affect acid and base reactions.
