Yes science can only accept and study what comes to it's notice through scientific methods.
Or otherwise said: that which can be shown to be actually real.
Ideas have a detectable impact even though they have no detectable manifestation. Ideas are real but not amenable to scientific study. Similarly God and His words can be real and have detectable impact.
Ideas have material underpinnings in the form of neurons firing in a material brain.
Ideas don't exist independently of material brains. And they certainly don't have the capacity to "do stuff".
The contents of ideas exist only as abstract models inside people's heads.
If you are saying that gods are analogous to such abstract concepts that only exist inside people's heads, then I'm inclined to agree with you.
Then maybe stop complaining?
As long as we can agree that science in some areas is only the educated guesses of people without consideration of what Poseidon or Graviton have told us about those things.
Your continued insistence on trying to raise up your god-claim, only by trying to push science down to a similar level of make-belief, is not a good way to make your god-claim sound more convincing.
I agree, but people like yourself have forgotten exactly what science is
I most certainly have not. It is the study of the world through verifiable evidence, in an extreme nutshell.
and like to see it as the only source of what is true and what can be known about the universe and anything.
If you have a better, or equally good, method of inquiry, you are very free to share it and demonstrate its success.
If the "alternative" to scientific inquiry concerning the natural sciences, would be a method of inquiry that is not based on verifiable evidence and testable prediction though... then I don't really see how it could ever produce better results, or results even remotely equal to what science does.
No I'm just pointing out that people have lost perspective of what science is.
Sounds like you are one of them.
