I find it perplexing that in situations like this there is the automatic leap to the supernatural. In most other instances (aliens, bigfoot), people go through a progression of natural explanations first and discount the far-fetched claim. However, when one makes a claim that a god or angel is "watching over" a person or that they heard an angel talk to them, everyone nods in agreement. Never mind the fact that in this case, the voice could have been a last gasp from the dying mother, or another person in the rescue effort, or an on looker, or etc. etc. etc. To me it speaks to a sort of desperation to find anything at all to justify a belief. Why can't individuals just be happy the child is alive and sad that the mother died instead of always trying to link some fanciful claim to whatever god they happen to believe.
