Early scientists had little to no understanding of science hence them being early in the timeline. They understood all the science available but they did not know what they did not know you know?
Most early scientists were clergy because early church members were so devout that they believed the Bible to be the penultimate truth. What can science possibly do to damage the truth? It wasn't until recently that religion became fundamentally anti-science because scientists began uncovering a truth that opposes their religion.
Fundamentally, of course, it doesn't. The Bible, read properly, doesn't oppose scientific endeavour. What it comes down to is this: if the Bible seems to contradict human wisdom, then one of two things is wrong. These two things are as follows, to whit:
1. Human wisdom, which is fallible at all times, and often needs correction. Look at this website, for example. The advocates of said site believe, against all scientific proof, that the Earth is flat. Either they are wrong (I think so), or the rest of the world is wrong.
2. Our understanding of the Bible may be wrong also. If this is the case, then it is our duty to make our understanding of the Bible correct. I think this has OFTEN been the case throughout history. To whit, our recent little discussion of homosexuality. No one disputes that that both Jewish and Christian authorities forbade sex outside of marriage (which is appropriate from my reading of Scripture). They also forbade homosexual marriage (which I think perhaps is INAPPROPRIATE from my reading of Scripture). Naturally, this had the affect of forbidding homosexual sex entirely. Since this appears to have come from a misunderstanding of Hebrew Scripture... well, you see where I am going with this.
The same can be said of other things in the Bible, and not just of social issues, but of matters touching on the scientific. Although the Bible is far from a science book, and makes no claim to be such, it does touch on the subject when discussing the Creation of the world. How could it not?
Now, I am no scientist, but it is my personal belief that when the Bible is interpreted correctly, and when science likewise is interpreted correctly, there can be no conflict between the two. Take your own positions. Neither they, nor you, are my problem.
