Hi Jimmy,
I'm not sure I'm fully equipped to satisfy your curiosity all by myself, but I'll give a try to addressing your key points. Let me preface by saying that these are my own cogitations on the matter, and may not be fully representative of nor aligned with the most current work in the various research domains we touch.

From your OP onwards, it seems that inference is central to the development of belief in the supernatural. As one of the articles suggested (and I am paraphrasing here), those creatures who infer the movement of a blade of grass as a predator have a built-in system to avoid being eaten.
However, inference is just a form of logical deduction: blade of grass --> could be predator..---> run. Therefore, would it be reasonable to assume that these creatures have a system of logic already in situ as a central part of their neurocognitive architecture?
Inference is definitely critical to these belief systems, and we very much are born with these logic circuits "in situ." The experiment with the infant who startled at a chair but not a human supports that suggestion rather strongly. A lot of work has been done in other animals where, for example, new borns show a fear of snakes or heights. This suggests that non-human animals have similar neurocortical predispositions and tendencies.
What I do wish to point out, though, is that the innate ability to infer and perform this type of logic is only one part of the larger collection of human mental abilities and predispositions which ultimately lead to these strong tendencies toward belief.

If so, there must be cases in the animal Kingdom , where there are correlates of this type of deduction. Large apes would be excellent subjects for research in this case. I just wondered how good their inference powers would be so scientists good work out a 'threshold' of inference making that would lead to increased survival rates or to point out a predisposition towards the natural or supernatural forces. Do large apes feel awe, helplessness, transcendent joy? Are their scientific methods to show these beliefs? Or are there methods to detect parts of the brain that 'light up' when humans feel these emotions?
This is a very interesting question, and TBH, I don't really know. One problem with doing such measurements in non-humans is that we cannot tell them, "Okay... think about god" and measure them in an MRI while they do. The communication barriers are pretty profound, whereas in humans, we can use our communication skills to properly setup the conditions of the experiment and get some solid data. There are several factors when conducting such work. For example, you need to have a shared definition of your key words, and the participant needs to fully understand your meaning before the test begins. That's a bit of a challenge when working with other species.
Additionally, even once we've mapped certain brain regions in humans with steps such as those described above... once we know which brain areas light up for certain very specific thoughts... that will only give us a slight clue into the overall phenomenon since (IMO) the effect/output being described in this thread is a "the whole is larger than the sum of the parts" phenomenon. Finally, once we understand this all in humans we will certainly be much better prepared to understand it in animals. Just recall that animal cognition and neural activity likely won't map one-to-one to human cognition and neural activity, despite the certain overlap in these processes we share in various degrees with these animals.
My own speculation, though? I'm pretty darned sure (that if we pin down that this is all explainable as a neurocortical phenomenon based on genetic predispositions in humans) that other non-human primates with a close relationship to us will be predisposed to these same things... that they will also have a "deity-esque" understanding of the universe... likely polytheistic... with super non-understood powers describing the rain and thunder and the cold and the heat, etc. I would find it surprising, basically, that we as humans have all of these biological mechanism inclining us toward belief and other non-human primates, or even non-primate mammals, would not as well. That's just my personal opinion, though. It could go either way.

However, the development, or evolution, of a social system with its concomitant social cooperation is central to the survival of a group. What are the mechanisms that encourage a group to form?
The short answer is the "You scratch my back, I'll scratch yours" phenomenon. We evolved in the trees, so our eyes are toward the forward of our skulls. This allows us to have better depth perception when swinging from tree to tree or judging distance between branches. However, we then started venturing out and ultimately surviving on the plains... flat land... and our eyes remained at the front of our heads. We began walking upright, which allowed us to see greater distances and over the taller grasses, but we were also now much more prone to attack from predators approaching from behind and above us... Basically, we cant' really see so well behind us because our eyes are at the front of our heads.
Now, think of just about any animal that is a common prey, like a rabbit, or a gazelle... you will see that their eyes are at the sides of their head, which gives them a much better ability to see behind them. Their field of vision covers a much broader angle than ours. When a predator approaches from behind a prey animal like this, they pick it up much more quickly due to the placement of their eyes on the side of their head, which allows them to run away and increase chances at survival. They evolved to have eyes on the sides, as this proved hugely beneficial.
But, humans... we have our eyes at the front of our head, as that brought us
other evolutionary advantages while we were primarily a tree dwelling species, but also some significant disadvantages when we left the trees... as we were much more vulnerable to attack from predators coming from behind us. Hence, the power of social grouping. What happened is basically this. We would be sitting alone, we'd get eaten from behind. However, when sitting with a group of peers, let's say 5 or 10 others... we suddenly could borrow their eyes. We went from having two eyes facing one way to having 10 or 20 eyes facing all different ways. The power of the social group is that the eyes of each group member work together. When one member of the group sees a predator, it sounds a call, and the entire group escapes. They sum the power of their multiple eyes for the collective benefit of the group. Those who cooperated in this way hugely out-survived those who did not... Those who stayed alone, or who lived in unhelpful groups, were consistently removed from the gene pool until we were left with a species hugely predisposed to social grouping and cohesion... Those in a cooperative and like-minded group simply had much better chances at survival over the eons.
Also, the group allows for greater success in hunting, as well as in help caring for offspring and kin. There are many reasons why group behavior is favored, and we see it across the animal kingdom in many different species, but especially in primates (which we humans are) who tend most often to exist in troops and packs.

In short, IMHO, inference, group survival and recognition/explanation of causality all seem to boil down to logical deduction. Humans seem to be born scientists. The thing is, how many other creatures also use deductive cognitive mechanisms?
Again, good question, but I also want to restate what I said earlier that that I don't think this boils down to one lone simple mechanism. It's a combination of several factors which come together to make these "super stimuli" of religion and deities. It's our predisposition toward inference, toward over reading causality, toward social grouping... our innate tendency to learn from and trust our elders, to accept what those in authority tell us, especially at a young age. It's lots of things, all coming together in this very strange way which has changed our culture itself. Ultimately, though... I can't help but to think that other animals do this also, it's just that it's much harder to measure such questions since we can't just ask a dolphin whether or not it believes in some sort of dolphin jesus or dolphin thor or dolphin zeus. ;)

Yet monotheism still maintains a hold on societies worldwide forcing them to be altruistic and charitable in situations where survival is paramount, but the means for it are a bit shaky.
First, bear in mind that the Abrahamic religions make up only about half of the worlds population. There are still a lot of polytheists out there.

Second, I think one of the things we're noticing now in the information age is that people are very often charitable and altruistic for reasons which have nothing whatsoever to do with faith or religious belief. They perform these positive acts and do these helpful things simply because they feel it is the right thing to do. That gives me great hope for humanity, and I look forward to us nurturing our innately positive attributes like these, while simultaneously rejecting some of the things which have caused our world such unnecessary pain and suffering, like belief systems and worldviews which conflict with those of friends and neighbors... beliefs and worldviews which implicitly further these tragic ingroup/outgroup mentalities. Basically, I'm for expanding the definition of "our group" into one that encompasses the planet, and not just "our local pack." That's where evolution seems to have trended, and I personally propose that it will continue in that same direction for many more years and centuries to come.
I hope the above gave some insight to your questions. You asked some really good ones, and I quite appreciate that. Cheers.

Jimmy - Your post kept returning to a common question, "Do animals have beliefs?"
With that in mind, I thought that you might enjoy this interesting article with exactly that title written by Dan Dennett back in 1995, published in
Comparative Approaches to Cognitive Sciences, MIT Press.
