Me: so zero is an integer meaning it means the number value equivalent of nothing but it’s an integer and actually represents a number that exists. Null means the number doesn’t exist and is not an integer.

    Zero is a value meaning ZERO.
    Null is a lack of any value. It's not even zero.

    SQL null is a state, not a value.

    Zero is a quantity and as such a value.

    And as you cannot compare a value like zero with a non value like null, 3 valued logic was born...
