Saying you want to get rid of religion is as absurd and inane as saying you want to get rid of numbers. "Religion" is just a fancy name for "worldview" and EVERYONE has one in some form or the other, you HAVE to if you expect to survive. In order to function in this world, every person has to put together some interpretation of the world around them so they can think on a higher level than that of a dog. Some worldviews believe the universe is fundamentally chaotic, some believe it is orderly, some believe reality is real, some believe it is an illusion, some are atheistic, some theist, some pantheistic. Atheism is just as much a worldview as Christianity, Islam, Roman Paganism, etc, etc, etc.
And I would be happy to accept having the best historical copies of each locked in a bunker somewhere for historians to study except we have seen where that leads, the Catholic church.
At this point in my life, seeing someone so proudly wear their ignorance on their sleeve just brings a smile to my face.
For the first 300 years of Christianity, the authorities did everything they could to wipe out Christianity. For those first 300 years the church had no authority to go after any heretical writings in any way other than strongly worded letters and had no idea who had copies and where they were. The Gospels and Letters were copied independently and sometimes haphazardly by inexperienced amateur copyists. Thankfully, in the last ~100 years there have been over 20,000 early manuscripts found and with so many copies it is trivial to find where all the errors are, most of which are simple spelling and word order changes. Almost the entire new testament has been reconstructed from fragments from before 300 AD. Other more complete manuscripts which agree with these earlier fragments have been dated to the fourth and fifth centuries. Had the Church done any editing it would have shown up as discrepancies in the pre-300 AD manuscripts. Critics for years accused the church of editing the Old Testament to fit the life of Jesus. The Dead Sea Scrolls put down that theory decades ago and likewise with the early manuscript evidence.
Even in cases where there WAS editing of non-scriptural texts, like with Josephus's mention of Jesus in "Antiquities of the Jews" where "he was believed to be Christ" was edited into "he was Christ", we STILL have managed to find copies in Arabic and Syriac that have the original text intact. The critics for years claimed that the Josephus mention of Jesus was an outright forgery, others claimed that it was original, but was clearly edited with a pro-Christian spin since Josephus never converted to Christianity. Textual criticism has clearly put the passage as "original, but edited" thanks to the hard work of countless researchers. Those wanting to do the same, but to the detriment of Christianity have tried for literally centuries, but continue to come up empty handed.
20th century Textual Criticism has the New Testament figured out to 99.9% accuracy. Any errors or ambiguities that remain have no theological significance. There's more errors to be found in many English translations than there exist between the original Greek and the Greek that was written 2000 years ago. Even more errors are caused by ignorance of 1st century Jewish and Roman culture, which is not always intentional given that most records from that time have not survived. Pontius Pilate, a high ranking official in the Roman government virtually disappears from the historical record without Josephus and the New Testament texts, that much has been lost from the 1st century. We are at the mercy of whatever has survived, often by accident. Technological masterpieces like the Antikythera Mechanism were accidentally lost for milenia until someone found the remains of one in a shipwreck. Apply the standards that critics apply to the New Testament texts to other texts from antiquity and you will find you are left with nothing whatsoever.
Not expecting to convince you, just pointing out what Twisted Sister said years ago, "If that's your best, your best won't do." You might concern some people who treat church as little more than a social club, but that's about it. As someone who genuinely investigated the pros and cons of Christianity and other worldviews, you're chucking peanuts at a battleship. People have managed to stump me before and I've gone and looked around and found possible and acceptable answers to their objection, but you're nowhere close. It's getting to the point I can just copy/paste responses I've used elsewhere.
