Would you agree that reasons to do things are founded upon knowledge about the outcome of an action. For example, let's say a person would not like the way they would look if they lost their teeth. Such person knows flossing and brushing their teeth would prevent their fall; so, such person flosses and brushes their teeth to prevent them from falling, and at the same time the person avoids an appearance they would not like. In this example, the person's reason to floss and brush their teeth (either not liking the way they would look if they had no teeth or mere precaution or any other reasons - i.e. they want to keep their teeth so they are able to eat or they want to avoid the physical pain of loosing your teeth, I dunno) is founded upon the knowledge that flossing and brushing your teeth prevents their loss.
Now, let's say a person believes in god. Following the logic presented in the previous example, such person's reason(s) to believe in god must be founded on knowledge about the outcome of believing in god. Be it personal satisfaction, or social acceptance, or psychological well-being, no matter the outcome, the person's reason to believe in god can only be a reason-to-do if the person knows about the outcome of carrying the action (believing in god).
Let's imagine now that there is a person who harbours in their mind the idea that there is a god but has no reasons to believe this; a completely possible scenario, I think. In this case, a reason for such person to believe in god would manifest only when the person knows about the outcome of carrying such action.
In all this examples, the person must be able to gather and store knowledge to be able to have reasons-to-do things. If a person did not have the faculties of gathering and storing knowledge, then the person would not be able to know about the outcome of actions, and therefore would be unable to form reasons-to-do things, in my opinion.
Following this logic, a question arises which is: is natural selection acting at the level of reasons-to-do things, or at the level of the faculties to gather and store knowledge, or at both, or are there any other levels we should consider first?
I think I mentioned in some previous post that you were oversimplifying things, and I hope you understand what I mean with these examples. It might be the case that natural selection acts only at the level of organs in a given organism - i.e. it affects the eye, but not the faculty of vision as a whole (at least not directly) -, or maybe natural selection affects only independent structures - i.e. the cornea, the iris, eyelashes, the retina - and emergent features resulting from the collective functioning of these structures are not truly under the effect of natural selection. It might even be the case, that some features of an organism do not affect its fitness and can be passed over generations until one day such features might affect the fitness of the organism that has them. It might be that the faculty to form reasons-to-do things, which is dependent on the faculty to gather and store knowledge, is evolving not under the effect of natural selection, but some other force(s) (bottleneck events, genetic drift, artificial selection, etc).
All this might be out of topic, but again I just want to hopefully show you how complex is the topic you are trying to discuss, and how lightly you are arriving to your conclusion. So, I think that a better place to start is to demonstrate that natural selection and reasons-to-do things can actually be discussed together because it might be the case that there is no relationship at all between the two.
