While I wouldn't go as far as you are in your assessment, in a simplistic sort of way, you are correct. But we all know that it was a lot more complicated and involved than that. So even though your assessment may be correct simplistically, it fails in the broader sense.
I use the analogy of the whisper passed to each around a circle. By the time the original whisper gets back around to you, it has changed significantly. We have all played this simple child's game when we were kids.
These were ORAL traditions being taught, and by imperfect men no less. They were bound to make mistakes because those men had free wills to shape their messages and teachings to satisfy their own biases and agendas, and limited by their own understanding, just as you and I do each and every day.
By the time they were finally written down, IMHO most of the original teachings had changed significantly.
In order to give it even a semblance of validity, they wrapped it all up neatly in a little box called the bible and proclaimed it the undisputed inviolable Inspired Word of God.
But we are finding more and more evidence that it is NOT the Word of God, but rather the Word of men that it is the Word of God, i.e. the discovery of The Dead Sea Scrolls by the Essenes at Wadi Qumran.
If people are so willing to take the bible founders word for it and be sheep, then that is their prerogative since they have free wills, but IMHO the critical thinker, the scientist, the observer of reality, the one not willing to blindly jump off the cliff just because it is the fashionable thing to do, the one really seeking the Truth, will use every tool available to get to it, including the ability to be patient and wait for further evidence, and be unbiased so that he can see and examine ALL points of views.
