There's a note at the top of the page that explains some of this:
"Creationism" can also refer to creation myths, or to a concept about the origin of the soul. For the movement in Spanish literature, see creacionismo.
The article attempts to give due weight to relevant sources.  If you believe that there are important sources that have been left out or that were not given due consideration, please do point us toward those sources (and you are, of course, always welcome to add material yourself, or discuss proposed changes).  Thanks.
