I didn't say that I know all of that stuff. I said that I've met Christians who know all that stuff. They write books that I read and give lectures that I attend. That was in direct response you claiming that you've never met any Christians who know the history of the bible.
I do know enough to know that much of biblical history is debated, and I highly suspect that the versions of biblical history that interest you most are the ones that put Christianity in the least believable light.
What would make you think that? On the contrary, as a Jew (and atheist) I was rather amazed to learn how soon after Christ's death his story was written down. As a result of this and other studies, I now accept that there probably was a preacher named Yeshua on whose actual life the Christ story is loosely based. This is a complete change from my prior understanding that the whole thing was a myth. In fact, I find the actual story not only fascinating, but rather supportive of the Christian version of events. I mean, the stuff was repeated orally among the people who did witness it, and written down within a couple of generations thereafter. Obviously it made a big impact on each generation of people. In fact, I think it's the most compelling evidence in favor of Christianity, and think it's really weird that instead the establishment has promulgated this set of lies that anyone can easily disprove, that the gospels were written by eye-witnesses.
Since I am not an expert in this field, and know zero ancient languages, in all areas of dispute I accept the currently accepted view of the majority. For example, I understand that the mainstream view is that there was such a Yeshua. Since I have no plans to pursue a doctorate in this field, I'll just accept that as the best current understanding about that. So, again as an example, I don't think any reputable scholars, Christian or not, think that the gospels are eye-witness accounts. Yet millions of Christians think they are. Someone is lying to them. I think that's wrong.
I don't dispute that there are a few Christians who know the Bible and its history, but they are a tiny, educated minority. The average Christian hasn't a clue. For some reason, the average American atheist does. I think atheists tend to be the kind of people who think that facts are important, and see the world through the lens of curiosity, people who think that factoids matter while Christians tend more to the faith/emotion/salvation end of things, that what matters is the relationship to their savior, not who told His story or when.
