Thousands of writings existed. Some of those were successfully hidden, some were destroyed. Of the ones destroyed, some were quoted. The ones NOT quoted is what you find impossible to allow into existence.
I never said that it was impossible that some "heretical" manuscripts existed at one time but were destroyed, just as undoubtedly some "orthodox" manuscripts existed, but were destroyed. In fact, I specifically said above, " I have no doubt that there may have been SOME "heretical" documents that failed to survive, even as there were very likely SOME "orthodox" documents that failed to survive." Allowing for their existence is one thing. Presuming to know their contents and use them to bolster an argument is quite another. The question we are discussing does not concern hypothetical non-canonical documents, anyway - it concerns the canonical documents and the way they were viewed at the time of their initial circulation, not centuries later in the time of Constantine.
Are you aware that Constantine was a pagan member of the cult of Sol Invictus? His predisposition to THINK in terms of Greek characterization thus paganizing christian theology is NOT A STRETCH!
No, I suppose it's not. So what? Whatever happened in the time of Constantine has nothing to do with your original premise, which was that the canonical Scriptures were seen as nothing special by the people who originally received the autographs, centuries earlier. Those people, you claimed, saw them as of little value and presumably used the autographs to wrap lunches, line birdcages and the like, even though they made and circulated thousands of copies before doing so. Whatever happened in that regard was long finished before Constantine was a gleam in his father's eye. Did Constantine contribute to some "paganization" of Christianity? Possibly so in some areas. But that's an entirely different topic than the one we started out talking about. If what you are trying to imply is that Constantine sat around with a bunch of potentially canonical books and selected the one he liked and destroyed the others, I've seen no support for that theory - or for that matter that Constantine had anything to do with establishing the canon, which was pretty much in place before his time - outside of popular fiction.
