Great question! I went to Answers.com and found the hacker slang definition of creationism. I definitely subscribe to this:
The (false) belief that large, innovative software designs can be completely specified in advance and then painlessly magicked out of the void by the normal efforts of a team of normally talented programmers. In fact, experience has shown repeatedly that good designs arise only from evolutionary, exploratory interaction between one (or at most a small handful of) exceptionally able designer(s) and an active user population ” and that the first try at a big new idea is always wrong. Unfortunately, because these truths don't fit the planning models beloved of management, they are generally ignored.
In case there is any confusion, let me clarify that
*I* am the "exceptionally able designer" and
*you* are the "active user population."
But the first and simplest (and on-topic) definition is this one:
Belief in the literal interpretation of the account of the creation of the universe and of all living things related in the Bible.
Does this sound like you? In any event, looks like just another case of a word having more than one definition.
The Wikipedia entry is very detailed, an interesting read.
