The contention by evolutionists is that intelligent design is just creationism with a new name. This accusation reveals a lack of understanding of the difference between biblical creation and intelligent design.
Creationism is the body of knowledge about origins based on the teaching of the Bible. Everyone, even Christians, understands that in our present maligned concept of the separation of church and state, the ACLU will sue any public teacher and school that attempts to teach the Bible and creationism.
In contrast, intelligent design, while consistent with what the Bible teaches, is not derived from nor does it teach the Bible. The subject matter of I.D. has arisen from a scientific investigation of nature. Thus it is science and can be tested. The science of I.D. shouldn’t have to come in through the “back door.” It qualifies to be included in science curricula just like all other scientific observations of the natural world. The fact that its conclusions point to a Designer is not relevant unless it is your intent to also exclude from science any evidence that might imply that a Designer might in fact exist—which is not science, but bias. Science seeks to looks at (all) the evidence that exists, and goes from there.
