Rather than a question of adulthood vs childhood, the reality is that humans evolved certain traits and abilities that mean superstition and religion are in our nature, for better or worse, like it or no.

Humans had to become adept at determining the intent of other humans and of animals to the point where we tend to anthropomorphize animals, inanimate objects, even concepts like justice and luck and fate.

We evolved mechanisms to avoid harm by remembering past experiences and predicting future ones. Though flawed from the standpoint of rationality, these adaptations were enough to prevent extinction of humanity at large, while leaving us saddled with numerous cognitive biases that leave us more likely to believe unfounded claims of a spiritual nature.

The antidotes to irrational, superstitious thinking are knowledge and critical thinking skills. It takes time, effort, and dedication to gain the upper hand against our nature.

It may be impossible to completely overcome our nature. Still I do hope we are able to set aside the most harmful manifestations of our nature: dogmatic thinking and religious zealotry.
