The persons having the OBE observed that their consciousness was active and observing things from outside their body and while their body was pretty much dead on an operating table.
So a human person "observed their consciousness" ... ? What did their consciousness look like? How did they measure it? Or did you mean to word that differently? How does one "observe their consciousness?"
"Pretty much" dead isn't dead, right? So what we're talking about here is brains doing things that brains can do. I've had many dreams where I felt like I was above my body, but I wasn't near-death. I was just dreaming.
These people recorded in their memory what they observed during this time.
Another strangely worded statement. These people "recorded in their memory" ... What does that mean?
So these people were in a room that the were actually in, and "recorded in their memory" things that happened in the room they were in. This is remarkable because ... ?
After their body was resuscitated they told their story and the people who were there confirmed the story and so confirmed that the persons claiming an OBE really had an OBE.
So nobody witnessed any disembodied minds?
So, let's summarize here.
Some people have "OBE experiences" when they are close to death and their brains are shutting down.
Some of these people can accurately report things that occurred in the room they were in, supposedly at the time their brains were shutting down.
Some of these people feel like they are floating above their bodies.
When the people wake up, their reporting of what happened in the room they were in, matches the reporting of what happened in the room by other people who were in the room at the time.
Let's just assume all of this is correct.
So, from this, you've concluded that:
-That consciousness is separable from the brain as a "disembodied mind."
-That there is some afterlife in which these disembodied minds live on (as 'spirits'?)
-This afterlife takes place in, and was created by the specific god of the Bible that you worship.
-That having an "OBE experience" is direct evidence for your religious beliefs.
-That a brain is at it's most lucid at the time it is dying.
Even though:
-Nobody has ever seen nor demonstrated that minds can exist outside of brains. Even in these cases you cite, nobody observed any disembodied minds floating around anywhere in the room.
-That when a brain is damaged, the mind is also damaged.
-That the people having these OBEs were merely "near-death" and not actually dead
-That upon closer inspection, many of these stories turn out to be far less extraordinary than first claimed
You also don't seem to understand that an "OBE experience" is just the experience. It isn't confirmation of the whole host of things you seem to believe about them. So saying "OBE experiences are real" just means that someone experienced something that we identify as having the characteristics shared by others having the experience. But you don't seem to realize that nothing is really demonstrated from that. All your work is still ahead of you to demonstrate all of the things you believe about them.
