In your reality-denial doctrine in attempt to allow the fantasy of supernatural magic, there is a false equivalence where everything is reduced to only an idea. Other than a doctrine, this type of metaphysical idealism can also be considered to be a long falsified hypothesis.
Humans are not "an idea", neither is evolution. They were observed and discovered. Beyond the fantasies of the human mind is reality. It is not because our brain receives partial signals from the senses that it receives and interprets in a way compatible with its biology and neurology, and that they can be distorted by the mind, that the signals originate from the mind (or whatever "higher self" one imagines to be separate from the brain, or from a dimension of collective ideas).
Of course, acknowledging that there's a physical reality that the human mind is incapable to alter without physical means, may discard your magic aspirations... Interestingly, the fundamentalists of other religions also often attempt to construe facts as ideas, especially if their particular doctrines also rely on modern interpretations of ancient mythology that they would like to posit as knowledge. Your magical doctrines are ideas, however.
