"Science" has already disproven the Bible. Let me explain why I am still a Christian:
In the 1820s, an archaeological dig in Babylon discovered that, beyond any doubt, Nebuchadnezzar was NOT the king of Babylon during the Babylonian exile.... His brother was. There was no way to resolve it, the matter was settled. The Bible was wrong.
90 years later, further archaeological digs in the same area discovered that, while Nebuchadnezzar's brother was, indeed, King, he spent most of his time out of state, leaving his brother as the vassal King. Armed with this knowledge, we then look at Daniel 5:29, where Nebuchadnezzar promotes Daniel to "third highest" in the kingdom, and it suddenly makes sense... Nebuchadnezzar himself was second highest.
The Bible was right all along, but for 90 years, the world had "solid, incontrovertible evidence" that the Bible had a factual error in it. If you were a Christian at that time, and you were aware of this error, would you have abandoned your faith? Would that have been the right thing to do?
"Science" is never 'fixed.' The "Science" is never "settled." The moment it becomes settled, it ceases to be science and becomes Dogma. GOOD science says this: EVERYTHING is up for debate. And always will be.
Given the facts, then, if the Bible were "absolutely proven false by science," I'm going to stick with my faith. Because even if none of the Bible is true, even if God doesn't exist and Jesus never lived, Christianity is still a great way to go through life.
But I am personally convinced that Christianity is True, and that Jesus is alive.
