An idea by people living in total ignorance
. Instead of doing proper research and looking for imperical evidence, ID supporters look through the pages of the Bible
for already answered questions. This might indicate the well observed "since I can't understand it it can't be true"-syndrome.
The other alternative might be the simple desire for convinience. ID-supporters don't want to write 6 page essays about how the cell works, just to be graded 3/5, but rather "God did it and that's fine by me" and getting 5/5.
