My hypothesis

[ronedee]

Religion is like a parasitic organism and its ideal environment is an ignorant society. It is dying in our information age.

Two or more religions can form a daughter religion and over time a religion will reproduce itself with variation in a population according to selective pressures (known scientific facts).

This model predicts that many religions should appear spontaneously in ancient history (no selective pressures) despite low population and that religion should go extinct in the near future despite high population.

So essentially, the population of evolution deniers is dwindling according to principles of evolution.

The problem with your theory is that the "information age" has not given any info about the nonexistence of God. So, religion will thrive until it does. And if extinction is in the cards, it won't be because of Christians. It will be in spite of them.
