I don't see how science could ever accept creationism. Science only accepts concepts that are based on the scientific method. Even if all scientists accepted it, creationism would still be no more than the religious beliefs of those scientists.
Creationists seem to be trying to find evidence for something that people once accepted without question. If they find no evidence, they will have faith to fall back on. If they find evidence, it wouldn't kill God, it would only kill faith, the significance of which would be altered greatly. The best non-creationists can do is attempt to show that the events in the Bible are implausible, and in some cases find evidence that goes against what the Bible says, such as evidence supporting evolution rather than a six-day creation.
Creationists will begin to think scientifically when they find that they can mold their own beliefs to fit the evidence, rather than forcing themselves to do things the other way around. I wonder if such people could still be called creationists.
