Not to mention that many of these intermediates are conveying messages from various very different and most of the time mutually exclusive, gods. With no way for their audience to properly distinguish which one is correct, if any.
As has been said so many times: the can't all be right... but they CAN all be wrong. And considering that all of them make he same type of claims based on the same type of non-evicence, chances are rather enormously huge that all indeed ARE wrong.
Also, if I were an omnipotent god and would rely on "text" to pass my message on to humans through the generations... I wouldn't be "inspiring" ignorant goat herders into writing on my behalf while relying on their own personal interpretation....
Instead, I'ld create the book myself. And I wouldn't make just one copy and give it to the least credible people I can think off. Instead, I'ld create a copy for every community on the planet. And I'ld create that book out of indestructible material. And I do mean indestructible. The kind of indestructible that a 25 megaton nuke detonated 5 inches away wouldn't even dent it. Being omnipotent and all, that shouldn't be a problem.
Imagine Columbus arriving in latin America, discovering native tribes there and finding out that they have a copy of the exact same book holding the exact same text and made from the exact same indestructible materials....
But no... instead, we supposedly have to rely on copies of copies of translation of copies of copies of translations of copies, originally written by ignorant goat herders who didn't even know that the earth orbits the sun and who apparantly were only aware of what was happening in a 300 mile radius - and even managed to get some of that wrong.
