The Claims of a “god-something” Need Belief?

Why are gods/deities even concerned with belief? As if they truly wanted belief so bad, they would be real, not ultimately hidden, and demonstrate in reality, more than just mental projections, of which they are now; they would show themselves, and we all would believe. Therefore, we can rightly conclude, with no evidence of them at all, that belief in god(s) is the thing people do when playing at reality is valued more than understanding the actual “natural only” nature of reality.
