Before Christianity there was slavery by many civilizations (pretty much all of them) and when Christianity became a dominant religion (in the Roman Empire) the first act by the new Christian leaders was to... ban slavery. And again when slavery was reintroduced to the Christian West (by non-Christians) the first and strongest abolishionist movement was in the Churches (the Anglican being the first).

Leviticus also gives the "Golden Rule" in 19:18 and universalizes it in 19:34 (Matthew 7:12, Luke 6:31, and Luke 10:25-28 also repeat it). Did the Bible borrow the "Golden Rule" or did the "Golden Rule" come from the Torah (which a far amount of the Bible also comes from)? No civilization prior to the rise of Judaism had a "Golden Rule", so it appears more likely that it became known through Judaism.

"The bible took from man, the inherent goodness..." You kid right? Men in the early ages were brutal, savage, and selfish. Men defined themselves by family, tribe, or sect and viewed all else as threats. The only things that prevented mass slaughter by ancient man were lack of effective weapons to kill each other and plentiful resources (food, shelter) to wage continuous war. Chrisitanity created a path to, and creation of, a universal brotherhood of man.

"Or maybe if the bible had knowledge in its pages that spoke far beyond what a 3rd century man would know? Such as the heliocentric model of our solar system, or germs or atomic theory?" As you will notice few Christians find the Bible as infallable.. oh you didnt, guess you should become a little more aware of what is going on in the world and what Christians really believe (and not what you wish to project upon them). If you read the Bible you will notice it doesnt actually state how the universe moves (it was men of the Church who created the Earthcentric planetary movements).

The people during the Enlightenment had no clue about atomic theories either, should that cause us to reject all of the philosophies created during then? You again take another quote from the Bible, one that very few modern Christians use and yet there are more Aethiests (China and Vietnam) who make their women second class citizens than Christians. Women in Christian countries had rights and suffrage before any other.
