It's worth noting that people applying the Bible have claimed certainty about things and then reversed their position quote a lot, too (certain dates for the end of creation are the most dramatically obvious case, though there are certainly cases of other factual and moral beliefs drawn with supposed certainty from the Bible that have evolved over time, as well as examples of such beliefs where people claiming certainty based on the Bible have offered different answers to the same question at the same time.)

So the lack of consistent certainty is not a differentiator between science and the Bible.
