I've watched a few episodes with my girlfriend (this is the only even remotely interesting show on OWN) and found it to be a big waste of time. This isn't like Decoded or Mythbusters, it's basically a politically correct version where they do very little detecting and mostly just look for "miracles".

The 9/11 firefighters one was the most ridiculous. The man was clearly having a hallucination brought on by the incredible stress of being at the crash site, but they didn't want to offend him or other victims of that horrible attack so they said "we'll never know...". Yes you do know. People in stressful situations will manifest a hallucination of whichever diety they were raised to believe in to help them cope with the pain they are feeling. This is how nearly all born-agains come to be, they hallucinate because they are suffering in some way, they are "saved" and then they basically live the rest of their life with a mental illness that people are too scared to point out.
