Creationism is a philosophy, a world view.
And there is far more to say about it. About our relationship to it. And what those things mean / might mean to us.

So, in the Christian mythos God created us in the garden of Eden, then Eve ate from the tree of the knowledge of good and evil, and thus much of humanities woes came about in that one "original sin".
These few words denotes a world view, a relationship with the universe.

Evolutionism could be summed up:
"god doesn't exist, so long ago a single cell organism formed, and then humans evolved from apes"

But we don't stop there, we go into why and how we think all of these things came about.
In other words, we tell a story about our relationship with the universe.

And, as you stated here in this post, if we give lots of time to one, and not the other, then the one must be the correct view. Or, at least its the view that gets the most airtime in our heads.

BTW neither Creationism nor Evolutionism has many facts supporting it.
They are both mostly conjecture.
