Here are two thoughts regarding your comment that there are no credible explanations to counter the supernatural explanations:

(1) Increasingly there are explanations for some events labeled as supernatural. Brain research provides clues. *"Out-of-body" experiences can be duplicated by brain stimulation. *Some of the Biblical descriptions of "visions and messages from a god" are similar to typical epileptic seizures (seeing white light, auditory hallucinations, etc). *"Returning from the dead" is now being examined with attention to the various phases through which a body dies. Dying is is a series of shut-downs and can sometimes be reversed before the actual final closure. Therefore, a recovery is not a "return-from-the-dead" ... because the death never occurred.

(2) The burden of proof lies with the claimant of the supernatural belief - not the skeptic who questions. Opinions are not proof. Supernatural believers need to ask better questions. Evidence will rule. Wait and see.
