My teacher treated Creation as allegory, not history.

Young Earth Creationism, Old Earth Creationism, Day-Age Creationism, Gap Creationism, Evolution Creationism (whatever that is), Intelligent Design, Modern geocentrism Creationists, Omphalos hypothesis Creationists, Creation science Creationists, Gap Creationists, Progressive Creationists, Neo Creationists, Creation literalists, Evolution Theist Creationists, Micro-Evolutionary Creationism, Progressive Creationists, Flat Earther Creationists, hard core Creationists?

no opinion or belief is sent to man from God contrary to natural knowledge.
