I think saying creationists came from Evangelicals is a worldwide conspiracy. There are NO transitional fossils at all. NONE! Hundreds of millions of creationists are keeping silent about the fact they are NOT descended from Evangelicals and are NOT themselves Evangelicals.
Hmmm...….
T'is a tough question.
It stands to reason that the creationist evolved first, since all Christians are creationists but not all creationists are evangelicals.
I'm also not using "creationism" in reference to new earth creationism or whatever the fundies think.
Although reading over my post, it is becoming readily apparent that @Sunstone is the correct one here.
I think that the idea that the world was created by one god or another probably came before there were people reaching out to other tribes about their religious beliefs.
