Its seems as though they (Creationists/intelligent design advicates) are attempting to legitimize their world view through science. To me, this is totally unneccessary. If there are problems with scientific theory, sure, these errors must be pointed out; however, I'm not convinced that's their entire agenda.
It seems they are trying to convince themselves more than anything. They have particular beliefs, so certain findings of science
must be wrong! Creation "science" and ID are just rationalizations which attempt to construct a scientific framework supporting those beliefs.
And it is not "unneccessary" -- it is futile. Science goes where it goes, and so far it is not supporting those fundamentalists' particular religious beliefs. It is disproving many of them.
But for some reason, they have to see
every claim of the bible as accurate, hence the support for a literal ark even though science disproved pretty much all of that 200 years ago.
Again, we see that creation "science" is the exact opposite of science.
