What I am saying is that there is a difference to being narrow in your view of things, and open in your view of things. There is a difference in being blinded by your own arrogance and open to understanding.
Humans don't have all the answers and might not be able to find them all. Our minds can only understand and perceive so much.
For myself I don't take the view so black and white as you. In my opinion you are superficially looking at faiths of the world like most and therefore seeing contradictions and so they are all wrong.
I have two comments on that.
If you look at the words of the spiritual leaders and not the mumo-jumbo (Buddha, Hindu Guru, Kabbalist, Christ, Rumi) you find a lot of similarity. There is a common thread of oneness of everything, selflessness, compassion, love, harmony, denial of self, and many more commonalities.
(In fact much of what the ancient Indian Spiritualist and Kabbalist and Sufist taught are showing to be possibly accurate by modern science from big bang, to worm holes, to the holographic universe, to everything literally being one though it appears separate, to the wholeness of all, to it all coming from nothing -which should be understood as a dynamic eternal nothingness not in the sense most think of it).
The geography, language, rituals, superstitions, clothing, dogma, and supernatural explanations are all just lines to make boxes for everyone to fit into. This is the superficial mumbo jumbo and was not taught by the spiritual leaders.
There is an old Indian story:
There are six people in a dark room and one moves to the center to hit an object. He says, "It is a long bumpy thing with slim at the end." Another man moves to the center and says, "No, it is large and wide and leathery." The other man comes to the center and says, "No, it is short and furry and soft." The other man says, "No, it is like five rocks sitting on the sand." The next man says, "No, it is beating thump thump." The last man says, "No, it is flappy, and rounded and soft."
Then, the lights turn on and they see they have all found different parts to the same whole ---an elephant.
FYI: Ancient people were capable of figuring out all kinds of things. The Mayans and Egyptians both had highly sophisticated understanding of the cosmos and the human body. Further since these ancient peoples of the world lived in nature constantly, not in front of computers or TVs or phones, they were not disconnected like many of us today and so could understand nature in ways that would evade us.
