This statement is made from the assumption that God doesn't exist and that all religions are equally false. From my perspective, I would argue that if you reset the world, yes, purely man-made religions would disappear and be replaced by different (man-made) ones, but ultimately God's true religion would always re-emerge.

For example, in my completely biased opinion, religions like Scientology and Buddism would disappear on world reset to possibly be replaced with some roughly equivalent man-made belief systems under different names (or not). But Christianity (insert the "true" religion here) would persist on world reset (perhaps even under the same name), and the entire Abrahamic-family of religions would re-emerge under different names. They might not be known as "Judaism" or "Islam" or "Protestantism" but basically God would call Abraham-esque prophets to establish his religion, the religion would go off the rails, false prophets would emerge, people would try to restore the church to it's previous state, God would re-establish with new prophets, etc., and you would be left with hundreds of similar prophet-based religions all in the same family of religions, all worshiping the same God, all acknowledging a common set of scripture (which would have the same core religious beliefs as the pre-reset world did), all acknowledging a common set of (ancient) prophets, but with varying dogmatic differences due to aforementioned corruptions.
