In science, a theory is an explanation of some aspect of the natural world that is supported by considerable evidence gathered through testing and observation. Evolution is one such scientific theory.

Like the previous poster said. “Unproven”
There is no evidence for molecules-to-man evolution. There is likewise, no evidence for life from non-life.
But I will grant you the “theory” part. In fact, life from non-life is an illogical theory.
