Why do you even call yourself a Christian? You sound more like an undercover Agnostic or Atheist?
You have a large ignorance about Christians, no Creationists, and Intelligent Designers. The two are different. There are Atheist IDers, Agnostic IDers, Muslim IDers, Hindu IDers, etc. Creationists are Christians who fall into several varieties as well.
Perhaps you've listened to some and perhaps you haven't. I don't know. I don't sit with you every day and see who and what you listen to, but your accusations sound like something right out of an Agnostic or Atheist's mouth. Your views sound devoid of being properly informed of the above groups. Instead, you rail general and seemingly uninformed accusations at all them and lump them together as one.
Regardless of "accurate histories" the Bible has been acknowledged as a history book to some degree even by those who disbelieve in it. It accurately records events and gives a window into a culture far removed from us. Also, despite your claim that "accurate histories" were not a genre back then does not somehow mean it is all false. Edited to add: Especially the Supernatural events.
Edited to add: You speak about Christians picking and choosing what, etc. Yet, you turn around and do the exact same thing it seems? With science, with history, with ancient texts, etc.
Edited to add: Science is myopic and has been hijacked by naturalists who believe that the only what we can experience with our five senses is reality. That alone is fallacious because your five senses can tell you nothing about your mind, things like love and fear, etc.
Now you're conflating what Medieval Europeans felt was important to report in the sky with what was reported in the Bible? Dude, Chinese, Arabian, et al were just as religious and had sacred writings and still reported the Crab Nebula in 1054? I'm not following that argument you tacted on at the end of bringing up how the ancients viewed history? Besides, I easily went to Google, did a cursory search and found a Journal of Astronomical History and Heritage from June 2003, Vol. 6, No.1 that lists, at least three records found out of Christian Europe in 1054.
Here's a thought for you, the very fact they wrote it down or passed it on verbally meant it was important for them to share the information (events, places, things) that occurred in history whether they embellished or not. Don't act like our enlightened modern selves don't still embellish either.
Again, as I said, just because you went to college doesn't mean you know everything about a particular subject. I've gone to college for computers, art, multimedia, 3D, biblical studies, contemporary religion, and philosophy. I have both a BA and a Master in biblical studies, contemporary religion, and philosophy while having coursework in the other aforementioned categories. I do not presume to know every facet of philosophy, the Bible, and other religions just because I have two degrees in those areas.
