The people who have “sentiment towards a rock” are the Muslims or fetishists?
Invalid consideration. The human brain does this regardless, and people all over the world of any affiliation ontologically find sentimental value in otherwise entirely mundane objects by applying upon that object some form of identity - be that memory of an experience, or more elaborate outlines.
Countless numbers of humans keep some object of some now dead person and talk to that object when talking to the now dead person.
The abnormal examples do not “exaggerate the effects” of the normal behaviour. It is a different way to answer to the same stimulus. You cannot extrapolate without justification.
Yes, abnormal examples do exactly exaggerate the effects of normal behavior.
That is specifically what a neurological dysfunction is and one of the primary methods of identifying regional operation of neurological processes.
For example, again, we understand the correlation between the Fusiform Gyrus and the Amygdala due to Capgras.
Does that mean the normal operation of this relationship causes people to behave like those affected by Capgras? No.
It let's us know that the correlation is a normal operation of the brain when looking at faces.
What does that correlation do? It imbues various levels of emotion to the analysis of the visual information regarding faces.
The emotional conditioning of behaviour is a well studied fact in many aspects. But it doesn’t imply that a particular emotion be a fixed constant.
That is not what is being discussed, and I apologize for the confusion.
To attempt to clarify this for you, I'll cite a case study of an race car driver who avoided an accident for which he could not see, nor did he understand why he stopped the vehicle.
In brief:
"The driver couldn't explain why he felt he should stop, but the urge was much stronger than his desire to win the race," explains Professor Hodgkinson. "The driver underwent forensic analysis by psychologists afterwards, where he was shown a video to mentally relive the event. In hindsight he realised that the crowd, which would have normally been cheering him on, wasn't looking at him coming up to the bend but was looking the other way in a static, frozen way. That was the cue. He didn't consciously process this, but he knew something was wrong and stopped in time."

Now, this is entirely normal.
People have these kinds of interactions daily.
Does everyone receive the benefit of being hauled into a simulator to replay the events over and over to be studied by scientists who help identify what happened and why they stopped?
No; not at all.
People have to rationalize these processes usually entirely on their own ability.
Many will claim this mysterious compulsion to do or not do something as some divine intervention because they perceive no possibility for which they could consciously been capable of, as it appears to them, knowing about the event before the event happened and before they were aware of the event.
Again, emotions which are entirely neurologically normal permit the conscious reflection the ability to rationalize in association to conclusions which are not themselves representative of the events at all, but instead representative of the person's emotional relationship with the event.
"God saved me from getting hit by that car" is not a confession of reality so much as it is an emotional expression of that person's relationship to the experience.
More importantly, the neurological faculty provides such opportunities even beyond purely emotional compulsions to include simple processes such as object permanence.
The only reason we are capable of being capable of eventually producing the construct of believing that someone who is dead in front of us still lives on is because the human brain is capable of processing object permanence to incredible levels.
We can not see someone for decades on end and still full well understand that they still exist; that thought still processes.
"I can't believe they are actually dead" is a very common expression, and it is one many convey because their brain still hasn't reconciled the fact of observing their dead body (or the facts of that person being dead) and object permanence which will, for a time, continue to stimulate in the brain that the object still exists (just like the ball under the carpet for a toddler before and after they are able to recognize its continued existence).
If it were not for this neurological function, we would be entirely incapable of eventually attaching emotional want to the absence and then from there deriving the idea that they are somewhere still around because we "feel" their presence still.
We don't feel their presence; we still have their presence preserved in our brain because that's how we are able to understand that when someone is not in front of us that they are not suddenly non-existent.
The conflicting information of object permanence and the information of their body being dead provides a paradox in the brain which can (key phrase, "can") permit the individual to resolve the conflict through siding with the notion of object permanence rather than the information that the individual is dead.
The point isn't that there is some part of our brain which is the "religion" part of our brain - no such thing exists, just as there is no such thing as a "consciousness" region of the brain, nor is there a "magic trick" part of the brain.
What exists, however, are all of our normal operations and functions, which include all of the capacities through association, correlation, imbuement and stimulation of senses, as well as the creation of identity, self-awareness, empathy and pre-conscious processes.
All of which have a wealth of capability to provide plenty of stimulation which a person can ingest to interpret a metaphysical capability of reality.
We could effectively wipe religion from the planet in a thought experiment and just by the normal operation of human neurology it would be of no surprise to see it re-emerge because we cannot control the human brain in such a manner as to remove from it the
potential, as a species, to perceive correlations in reality as metaphysical relationships.
As long as there is the ability for that Formula One racer to have that experience, as long as there is the ability for self-awareness being correlated to emotional value, and as long as there is the ability for the brain to hold conflict with object permanence, then there is equally the
ability for a member of the human species to interpret the experience as some supernatural intersecting force to save their metaphysical version of their self (soul, spirit, divine breath, or any other name...)
Or, more simply put: as long as we have emotion, then we'll very likely have the ability to create, adhere, reinvent, etc... religion.
It's not as if all humans in the prehistoric era gathered together and equally decided that religion just seemed like the right idea to answer the observations and sensations they experienced.
Quite to the opposite; disparate groups of humans did this.
And that's rather simply capable as an emergence because our neurology permits such interpretation to happen even when the entire species is not interconnected in communication.
