For instance, diethyl mercury is known to be one of the most dangerous neurotoxin known to mankind (http://en.wikipedia.org/wiki/Diethylmercury). The consensus on the mechanism of action for this compound is that it's the oxidation state II mercury itself that is neurotoxic, but it's the alkyl groups that help it go across the blood-brain barrier. Look up the structure of thiomersal. It is an organic mercury compound that has an alkyl group directly on mercury, thereby giving access to the brain directly.
Similar compound, dimethyl mercury is also very notorious for its neurotoxicity. I do research in organic chemistry for living and a fellow organic chemist one time accidentally dropped a drop of Dimethyl mercury on her hand. It went through the gloves that she was wearing and onto her skin. Within several hours she was dead from what the doctors described in layman terms as "her brain melted". It is scary stuff. Some things about chemicals you don't necessarily have to do human clinical trial to predict that it'd be dangerous. If you have trained eyes you can just look at the chemical strcuture and predict its toxicity. However, as the good Book says, the love of money is a root of all evil. Once a big pharma company starts liking using a compound, they'll push for research that says it's safe even if it's not. That's just the way it is sadly.
1. Insult the stupid Christian
I've been reading your nonsense, and I must tell you. Go get an education.
I have a PhD in organic chemistry from UCSD. Do you consider that education? What higher degree could I have gotten?
2. Make a broad statement via the "begging the question" methodology
The entire source material of the bible is suspect, and is full of translation errors, etc since well, it was first translated.
We were discussing about whether the content of the Bible had been altered and whether any of the content have been proven wrong. So let's just use the desired conclusion as the starting point for the discussion: logical fallacy (beg the question).
3. Use lies when useful
Then it was translated some more, and then some of the "original" source documents were destroyed, so all of the "new" versions were then based on the original faulty translations....
A big plus if you can figure this out: Which books of the bible weren't mistranslated from Aramaic to Greek, and then into Latin, and then further mangled by "scribes" attempting to appease a few Roman Emperors and their view on what was and was not heresy as it applied to their divine right to rule.
All of the modern translations of the Bible (I only can testify about English and Japanese translations) were translated directly from Greek manuscripts for NT (possibly with an excpetion of parts of Matthew, which may have been written in Aramaic) and directly from Hebrew manuscripts for OT. I do keep hearing from skeptics that the Bible was translated many times successively, which is not true. I suspect that they get this idea from the Septuagint and Latin Vulgate. If the modern English translations come from those only, that accusation is partially true, but they don't. Besides, as I've stated, many Bible teachers consult the original Greek manuscripts before teaching so that any misguided English translation will not get in the way of teaching the Bible, and modern translations are very rarely off.
4. Switch the subject if you don't know the answer
As to which historical accounts in the bible have been proven wrong? That's the wrong question to ask. The better question is, "Given what we know of world history, exactly which historical events in the bible have ever been proven true?"
For starters, archeological evidence:
-Joshua in Egypt, Israel in wilderness, Jericho, king David, Solomon and their descendants who were kings, king Xerxes, king Cyrus, Babylonian conquer of Judah, Herod(s), Pilate, Mary & Martha, Churches mentioned in Acts.... I can't list them all
Scientific evidence
Although the Bible doesn't address scientific issues, there are somethings that are mentioned that we didn't know from science until the last few centuries: currents in the ocean, the earth being a sphere, water cycle in climate, mountain formations, origin of fossils, the earth suspended in space, material made of invisible particles, etc etc
There are tons more that I don't have time for. These are evidences in support of the authenticity of the Bible. Not proofs.
So, what part of the Bible has been PROVEN wrong? Especially the historical stuff. I'd love to know! Don't switch the Q!
If you plant to hate stupid Christians, these lessons in logical fallacy tactics should be helpful to you
