What is it about the concept of a deity that causes its persistence?

The concept of a deity, whether it is the Abrahamic God, the polytheism of the Greeks and Egyptians, the Pantheism of some Buddhist interpretations, or Einstein’s deism, has persisted throughout human history. There are almost as many concepts of deities as there are people. However no matter how much each concept is discredited, the deity seems to evolve in a way that eludes discrediting arguments so the believer may hang on to their particular mythology.
What is it that causes humans to hang on to this concept? Is it a feature of the concept or a feature of the human psyche?
