This is science and religion.
You are know a scientist in the field. You observe humans and note a difference in behavior: Some are religious and others are not.
So it is a fact, that there are religious humans. Then answer me this:
How can that be wrong using only science, reason AND logic?
Remember only evidence, reason AND logic!
Now I will tell you what happens: You can't only using evidence, reason AND logic to say that religion is wrong. How is that: Well, it is a fact, that their behavior is without evidence, reason AND logic, yet it is a fact, so it is real and a part of existence and how reality works.
Now what happens next, is always a variant of this however phrased: Don't you think, that we ought to... Or: I think, that we ought to...
But that can't be answered with evidence, reason AND logic alone. How is that? Because they are not alone in reality. The belief and it is a belief, that evidence, reason AND logic is the only thing real and existence besides the physical/material, is falsified by observing that some humans in some cases are without evidence, reason AND logic.
And it overlooks the IS-OUGHT problem. No one has solved that using evidence, reason AND logic alone. Neither science nor philosophy or indeed religion.
That is the end game and it has a name: Cognitive relativism.
BTW - real and existence are not scientific terms. They have no observable referent. They are at best only relevant in some forms of philosophy. You can do science without any metaphysical assumption. It is called pragmatism or instrumentalism and some variants are a form of anti-realism.
As far as realism versus anti-realism go, there are 3 possible approaches:
I am a realist.
I am an anti-realist.
I don't care, I just do science.
So here it is as what we share: If I cut you, you bleed. If you cut me, I bleed. We share, that we are humans, but are different as individual.
You are neither better or worse as a human than me or in reverse. That only counts if it matters and that is not evidence, reason AND logic alone.
As long as we can't agree on that, I don't mind being "wrong or what ever" in your view, because I know it is not based on science, evidence, reason AND logic alone.
