See the magic
When you look at different religions, they usually contain "magic." For example:
The Mormon religion contains the magical golden plates, the magical angel, the magical seer stones, the magical ascension of the plates into heaven, etc.
The Muslim faith contains the magical angel, the magical flying horse, the magical voices, the magical prophet, etc.
The Christian faith contains the magical insemination, the magical star, the magical dreams, the magical miracles, the magical resurrection, the magical ascension and so on.
The presence of "magic" is a clear marker for "imaginary." For example, how do we know that Santa is imaginary? Because (among other things) he has eight magical flying reindeer. How do we know that Jack and the Beanstalk is a fairy tale? Because (among other things) the story contains magical seeds. In the same way, how do we know that God is make believe? Because God is surrounded by magic.
