Isn't it a little tough to say that science will cease to exist if we allow ourselves to believe that a supernatural being had a hand in all of this? We should continue to pursue the how and to test what we think we know. Attributing creation does not preclude science. Even if we were to all agree on creation, the Creator obviously used extremely precise and constant laws of physics and nature to define the universe. The science lies in continuing to further our understanding of these laws.
Rather than outright denial or acceptance of a supernatural creator, we should continue to advance scientific progress. However, in the vein of proving or falsifying God, as you put it, years and years of science should eventually point us in one direction or the other.
For instance - here's a basic evolutionary flaw that evolutionists don't really like to talk about.
Let's assume that the evidence for an old earth is overwhelming, that the combination of the measurements of the expansion rate of the universe, color-luminosity fitting, and nucleochronology techniques combine to date the universe from 11 to 20 billion years old, right?
One of my Favorite Flaws
--Even crude mathematical models can demonstrate (and can be field-tested) that any species wishing to evolve significantly (into another species) would require a time period of at least one quadrillion years, a body length of one or fewer centimeters, and a generation cycle of no more than three months. Biology is more fun than math (to me), but it leaves excess room for debate (which is also fun).
Just because we see a cute collection of fossils doesn't mean that we can make the huge leap over clear chaos and probability theory chasms to say that they must have evolved into each other.
Shouldn't we discuss why, in the recorded span of human history, we have never witnessed even one single example of speciation through evolution? Only extinctions...
See? The objective data should lead us somewhere. In the case of the fossil record we've accumulated in the last century, i think it does.
