Idiot, by your own chart, the vast majority (33.32%) of the world ARE Christians following the Abrahamic God! But no matter, Muslims, Hindus, Buddhists and "other religions" follow the same "god", just under a different name and morphology.
You are an idiot.
To be pedantic, 33% is not a majority; it's a plurality. It would have to be greater than 50% to be a majority.
But between Christians and Muslims, the chart does appear to show that they, combined, make up the majority. The chart doesn't show Jews as a category, but between Jews, and the majority made up of Christians and Muslims, you certainly have a solid majority that recognize the only true God.
I tend to believe that many of the non-Abrahamic faiths derive their belief in some convoluted, indirect way, with some past experience involving the true God, but I have to admit that it is really not provable or even very supportable. I tend to think that they are the blond men who encountered an elephant, and each formed a different, inaccurate view of what the creature was like, based on just a part of the creature.
I.
It was six men of Indostan
To learning much inclined,
Who went to see the Elephant
(Though all of them were blind),
That each by observation
Might satisfy his mind.
II.
The First approached the Elephant,
And happening to fall
Against his broad and sturdy side,
At once began to bawl:
"God bless me!—but the Elephant
Is very like a wall!"
III.
The Second, feeling of the tusk,
Cried: "Ho!—what have we here
So very round and smooth and sharp?
To me 't is mighty clear
This wonder of an Elephant
Is very like a spear!"
IV.
The Third approached the animal,
And happening to take
The squirming trunk within his hands,
Thus boldly up and spake:
"I see," quoth he, "the Elephant
Is very like a snake!"
V.
The Fourth reached out his eager hand,
And felt about the knee.
"What most this wondrous beast is like
Is mighty plain," quoth he;
"'T is clear enough the Elephant
Is very like a tree!"
VI.
The Fifth, who chanced to touch the ear,
Said: "E'en the blindest man
Can tell what this resembles most;
Deny the fact who can,
This marvel of an Elephant
Is very like a fan!"
VII.
The Sixth no sooner had begun
About the beast to grope,
Than, seizing on the swinging tail
That fell within his scope,
"I see," quoth he, "the Elephant
Is very like a rope!"
VIII.
And so these men of Indostan
Disputed loud and long,
Each in his own opinion
Exceeding stiff and strong,
Though each was partly in the right,
And all were in the wrong!
MORAL.
So, oft in theologic wars
The disputants, I ween,
Rail on in utter ignorance
Of what each other mean,
And prate about an Elephant
Not one of them has seen!
