Zarathushtra brought on agricultural revolution

It does appear to be well established that agriculture was brought to Europe from the Near East.  I recall haplogroup J was one of the daughters of the mitrochondrial Eve and European clan mother, that introduced agriculture to Europe.  She says Zarathushtra's missionaries settled in Iraq, and as far west as Greece.  

Zarathushtra probably did compose at least parts of the Gathas.  But, whether he existed or not is not the point.  The point is that the Gathic literature was recorded at some point in the history.  There's more of a likelihood that he lived than there is Homer lived.  Jesus was a mythological figure.  I totally agree with your rundown of the scholarly placement of Zarathushtra, but Mary Settegast's work was not a crackpot thesis.  It was the thesis of her predecessors that there had to have been an ideology that encouraged the agricultural revolution.  Settegast is proposing that it was Zoroastrian ideology... which did in fact promote the settled life.  A lot of what the ancient Greeks have claimed about Zarathushtra had been written off, but later scholars have found them to be right.  For example, the ancient Greeks claimed the magi practiced metempsychosis or reincarnation.  This was written off until it was discovered that there was a regional form of Zoroastrianism that promoted reincarnation.  I'm not saying Settegast is right, but its worth looking into.  What would make her case stronger is if more of the ideology in ceramics from the agricultural revolution were understood, but little is at this time.  That's why I'm curious to know if anyone knows of any other interesting ideological patterns from the agricultural revolution.   

I'm not 100% sure what your question is or what your getting at, but she mentions agriculture spreading from Iran to Southern Europe.

She says the agricultural revolution began in the latter 7th millenium.  By this time patterns become more complicated like they could be ideological.  She says Halaf culture was a product of this Zoroastrian mission, but Halaf culture was replaced by Ubaid the pre-Sumerians.      

Sorry it was Hafian, not Halaf.  

These are some of her counter arguments:

There is no solid set of criteria to determine how well certain languages could have been conserved over extended periods of time.  Not only are different languages known to have changed at different rates, but as an Avestan scholar points out, religious or priestly language tends to be particularly slow to change, since religions are vy nature conservative.

Words change over time and a survey of “wheel” words in other Aryan (IE.) languages reveals meanings that are  often more symbolic than literal.  While the word for “wheel” in Avestan and Sanskrit is ratha, the related Latin word rota actually means “circle as well as “wheel” and the alternative translation of the Germanic rotho (wheel) as “sun” or “sky” takes the meaning of this root word directly into the metaphorical.  

The identification of copper sl*g at Level VI of Catal Hoyuk proves that molten metal was known as early as 6500 BCE.  

So everything checks out, except for exhumation and apparently fire cults are mentioned in the Vendidad.  She didn't address these points, so her theory definitely needs work, but I think its very interesting that ceramics could have conveyed and ideology which encouraged the settled life.  

correction: the Younger Avesta mention agriculture.
