Humanity is not very well aware of the nature of souls, it is true. However,
The "survival hypothesis"
does not qualify as a religion, but rather it is the simplest explanation for these 40 cases.
"The personality survives death, at least sometimes" is the simplest explanation for these cases.
"When an extremely improbable situation arises, we are entitled to draw large conclusions from it."

No I have not because Christ told me to beware of Pharisees like Saul of Tarsus (in Matthew 23) and I have no evidence that Saul was a "follower of Christ".
Hierarchy is not "the way everything works". It does not work that way in the higher realms.
Now you are trying to say that there are more gods than One.

I am trying to say that hierarchies are a fabrication of man and they do not exist in the higher realms. I am not sure how you deduce many-gods from that.
Anyway, I question the "teachings" of Pharisee Paul; Christ made gave us many warnings about Pharisees.
