Our ability to create fiction, retell the past, and speak of potential futures is what allowed us as homosapiens to develop into our species in the first place, and it is that very ability that is at the root of our propensity towards belief and religion (Harari 25).
If you're a deconstructing believer or former believer and you have not yet read "Sapiens" by Yuval Noah Harari, I encourage you to do so!
