Value can mean preferred which is inherently subjective. Objective value, is a mathematical value we assign to describe objective criteria. My height has a value of 5.5 inches. That's an objective value (so is my weight, age, and chemical composition), but it's not what we mean when we say people are valuable. The decision to value people is a subjective determination. Nothing has inherent subjective value. Theists in particular often confuse numeric or objectively descriptive traits with subjective preferences for certain traits. But it is a very different use of the word value. The first means a single choice among variables, the second how much a particular person or group likes some trait or group of traits.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
