If it is claimed as a mater of fact, yes. If it is treated as a hallucination, insanity, dream, fanbtasy, fiction, what have you, even a simple a priori blind belief, then no.
For if I make a statement of fact (such as "I can fly on my own," or "I am God" or "there is an angel in this room" or "the world will end on such and such a date" or "my dog can talk", etc.) you will ask me for a rational, verifiable proof. If you tell me there is God, I will ask you for proof; you bet.
First, I'm not attempting here to convince you God exist. I am pointing out that your basis for your position anti is logically flawed.
If you tell me there is God, I will ask you for proof; you bet.
And if you tell me that only that which can be known and proven by reason logic is real - exists - then I will ask you for your logical proof of that statement.
