Does anyone else here think that Satan was originally a Proto-Indo-European deity?
I don't - the essence of the Dark One can be found in every culture, so also in Indo-European ones. But I saw no evidence that the Jews took their concept of Satan from the Indo-Europeans, at least not the original one, as in the Book of Hiob.
The later, more dualistic interpretations seem to be partly derived from other eastern myths (e.g. the fall of angels), partly from Zoroastrianism (which would be an Indo-European culture). Is this what you are referring to?
There is some evidence that points towards it, such as the semi-false cognates between Romantic and Eastern languages like Sanksrit.
What do you mean by "semi-false cognates"? Romance languages and Sanskrit do have a lot of actual cognates, as they ultimately both have the same parent language. But what does that have to do with this theory?
There are some Indo-European myths involving dragons, bearing similarities to those of surrounding religions.
Dragon myths are very common, that's true. But well, I have to ask again, which concept of Satan are we talking about? As far as I know he was only associated with a dragon in the Book of Revelation, not in any Jewish text that I know of (except for the snake in the garden of Eden-story, if you wanna count that).
I think there's a good possibility that "Satan" was the central intellectual wind deity in their pantheon when the Indo-Europeans were in Ukraine. Satan became Wotan and then Odin in the North, Ea in the South, and Satang in the East.
When exactly were the Indo-Europeans there? How would that have spread to the Babylonians? And who is "Satang" supposed to be? I only find this:

Also, wind deity? I don't think a general wind deity has been reconstructed - I think I read about a reconstructed sky deity, but not wind nor intellectuality. What are your sources on this? And what are your sources for the linguistic relationship between the names you mentioned? I am a linguist and it sounds pretty unlikely to me to find relations there.
Now, what is really quite amusing is the fact that Satan became the word for "adversary" in Hebrew, while a variation meant "truth" in Sanksrit, which is an Indo-European language.
I told you before, "truth" is one of a thousand meanings that "sat" has in Sanskrit - the basic meaning is just "to be". And it happens often that words of similar pronunciation have different meanings in different languages without any relationship - there are only a finite number of sound combinations possible, and something as short as "sat" is bound to appear in many languages - in German for example "satt" means "not hungry", "having eaten enough", and "Saat" (same, but with long a) means "seed".
So, hardly enough evidence.
I know this sounds like some JOS bull****, but really, the more I piece together of this, the more interesting this becomes.
Yes it does, and without that disclaimer I might have ignored you for it.
