Humans do like patterns, and tend to attribute their creation to some kind of powerful being. That’s a teleological argument for God, an argument from design or purpose. Humans also have remarkable imaginations, but for the most part what they imagine tends to be amalgams of what they’ve experienced, except for perfection itself, which can only be imagined: that would be an ontological argument for the existence of God: God exists a priori. As your answer is related to both, I recommend looking up both teleological and ontological arguments for the existence of God in the Stanford Encyclopedia of Philosophy: plato.stanford.edu.
