I do not believe far flung tribes don't have their version of a shaman or whatever. //
I don't doubt that and thought I'd skilfully avoided the issue by using a sociable animal species as a model of a functional "society" with plenty to fear but no deity. I think a follow up point didn't get from thought to typing finger (phone keyboard!) to the effect that the "need" for gods arises when intelligence evolved above the threshold required for - how shall I put this? - "vivid imagination".
//The more primitive and unknowing a group is the more they'll attribute a greater power to that which they don't understand.

On a recent edition of The Big Questions , airtime (not enough!!) was given to atheism and one put forward the idea that "credulousness" can confer advantage to a mammal because, if it imagines that there is a predator, lurking around a rock, if it is incorrect, it doesn't matter and wastes only a tiny amount of energy taking a detour but, if it turns out to be correct then its detour keeps it alive, whereas the empirical mammal will take its chances because saving energy would have been the factor keeping it alive longer, if the population was iniformly stressed by famine, say.
Having said that, this ability to picture things in the mind, handle concepts like time, plan out future events ("I will go to the river to drink, after I've eaten this meal"), imagine potential dangers is a big advancement over mere reaction to sensory inputs. Whether it is an ability unique to humans is impossible to tell. They've communicated with chimpanzees and they can request food and beverage types well enough but whether words like "now, later, yesterday, tomorrow" - concepts with no physical presence - hold any usefulness or meaning for them, I don't know. If they cannot or don't then I'd regard them as below the threshold for theism. A discontinuity in your spectrum of "more primitive = more tendency to believe".
My stance regarding the other side of that threshold is that, the most "primitive" human tribes still have brain *power* exactly equivalent to our own. They only lack the education and time to work the world out for themselves. In the vacuum that is the absence of that knowledge, there is ample room to, as you suggest, attribute what they do not understand to higher powers.
