Where the Christian spirit fades, superstition grows.
Humans are pattern matchers and will identify patterns where there are none. Faces in clouds, mountain outcrops, etc. this lends itself to superstition. Nothing is special about Christianity aside from being regionally popular.

Now, what Jesus taught is one thing, but what people created is another one. What Luter revolted against, for example, were not the teachings of Jesus, but all superstitions that were created by Christians and deemed to be Christianity.
Even today, when you talk to Christians, many of them believe in various superstitions. So, frankly, the opposite of your statement might be true.
