Took a look Tony. Saw nothing specific enough to get a handle on. And it is a self validating system.

e.g. Take the Northern Lights...
Beautiful things said to be solar particles glowing in the atmosphere as they move towards the earths magnetic poles. That looks right to me.

But according to one old Indian Tribe in Wisconsin, they are gods holding glowing lanterns in order to aid fishermen at night.
How do you know whether or not that is true?
You ask an Indian from that tribe who subscribes to that belief and what he says is your proof?

A Viking would have told your that they were Norse gods. And back in that era, if a Viking told you something, you best not argue with him about it. Doesnt make it right, but living on is better than winning that argument.
