There are roughly 4200 religions in the world. All these religions cannot be true at the same time. But how does this imply that all are false?
Because the 4199 which are false use the same epistemology and evidence for their claims as the 4200th. So, even if it is true that at most one could be true, we can conclude that their claims are all equally reliable. Therefore, there is no rational justification to pick one and not another one.
If we consider all mutually exclusive religions of today and in the past, we can also conclude that there is a natural predisposition for humans to make up their own version of God. At least, the probability of randomly chosen religion X to be man made, is suspiciously close to 1. And God does not appear to do anything to correct the situation.
Add to this the fact that all of those beliefs are not equally distributed on the population of the planet, we can also conclude that people's primary epistemology is simply to pick the one they grew into.
Because of this, there is ovewhelming rational warrant to reject them all.
