I actually have contemplated similar conclusions and have been non-seriously collecting evidence that suggests at something similar. Indeed very interesting relationships nonetheless between “Master of Animals,” shiva, thor, Odin, yahweh, thunderbolt, stormgod, Cernunnos, Gilgamesh.
Not many people have connected Cernunnos to the same culture as the above entities. It is evidently quite certain when looking at the art of these cultures that there is a common thread and history. I think there may be oversight into that aspect compared to the writing and language. The way something is crafted is quite unique and the signatures are there tying the above together.
Indus Valley <> Viking <> Babylon <> Gaelic <> Irish/Scottish <> Vedic <> Abrahamic
These are connections that are quite curious indeed.
I’ve brought these things up and usually I just get assaulted as a conspiracy theorist or wanting to rewrite history.
All history is fiction anyway.
The only thing I care about is patterns and patterns have signatures, and to me, there’s a common threading of a specific signature that suggests a significant population and culture of same origin that doesn’t align with the reasoning that exists to explain otherwise disconnected cultures.
