Please state your position. Are you trying to make the case that a) NOTHING in biology makes sense except in the light of evolution. b) SOME things in biology only make sense in the light of evolution. c) for some things in biology evolution provides a plausible but not exclusive explanation. d) Everything in biology makes sense without invoking evolution.
You can DO things without them making sense. A cat can start a fire by knocking over a heater but does fire make sense to the cat? Fire only makes sense in the light of chemistry and physics.
Creationism doesn't need to "produce its own science".
Correction: creationism CAN'T produce its own science because there's nothing scientific about it. Creationism can't make sense of biology because it ignores reality. it's based entirely on myth.
If creationism could produce its own science, it might be taken seriously by science; it might be possible to teach it in schools. But as it is, all creationism can say is that science is wrong, which isn't much of a basis for education.
