If it is superstition, it is a threat to our survival, rather than an aid in securing it. Religion like science, is merely man's attempt to understand the world around him, and to manipulate phenomena in the environment for his own benefit. Obviously a religion or a science that was not true would not help him gain control over his surroundings. Anything that interfered with human understanding would reduce our ability to control the environment and ultimately reduce the probability of human survival. Superstition is not religion anymore than darkness is light.
Superstition is the exact opposite of religion because it interferes with that understanding.
Superstition far from being a good thing that helps man, is actually an evil thing that harms mankind. God put the tree in the garden and allowed Satan to come there because he wanted to test mankind. But God created everything that went into this combination, situation or environment. He intended for each element to be exactly as it was because he was all powerful and could not make a mistake. It is absurd for God to punish man after creating him.
