Hi Tito, welcome to Postflaviana.
I think that somewhere on the forum we have discussed the moon aspect, and yes I think that it may indeed be related. The problem in creating a new monotheistic schema is that one must select one aspect, or name at least, over another or many others. The Jews retained such as the lunar calendar, but there are also various remnants of prior solar worship.
Psalms 68:4 "Sing unto God, sing praises to his name: extol him that rideth upon heavens by his name JAH, and rejoice before him."
My reaction was to the article on versions of the "Yahwe," and wanted to throw in another alternative (Iah = moon god).
I think that the most important question (using our specific lens of analysis) is what was the primary goal? Was it to create a new and unique exoteric religion for whatever purpose and/or whatever name, or to advance a specific god (in this case of the Sun) because there are true believers that must be satisfied?
If you look at Amun, he took on additional characteristics. From Amun-Ra to Amun-Min (the penis Amun). Why? May be with the change in the population make up to please more Min followers and keep the peace, conquest of (fertility) min followers, to show more universal characteristics to the one god (Amun), among others. The Bible is loaded with God taking on attributes.
It is our thesis, under the Genesis of the False Dialectic (Jews versus Gentiles) of Western Civilization, that Judaism was synthesized almost 100% as a inversion of prior cultural practices and laws (the 613 Mosaic Laws minus the 10 Commandments) and the moral inversions (from the Mesopotamian corpus) in the Genesis creation mythos. It is our thesis that Judaism was cynically created, for among other reasons, to act as a useful foil for geo-political purposes, and it remains so till today as discussed by James Carroll in his Constantine's Sword. To wit, Catholic theology and the papacy (until JPII) has overtly stated that the Jews are needed as just such useful foils for Christianity, therefore, please don't kill them all. It's all an advanced form of "divide and conquer".
Why the cynicism? It could have been syncretic, that is to say organic and evolutionary. The Canaanites could have adopted Egyptians gods (and they had many) and vice versa like the above monotheistic, the one, Amun taking on different characteristics. Looking back over the distant past without a paper trail of evidence it might seem like something mysterious is going on. This does not of course preclude political forces (elites) from favoring one over the other depending on perceived and actual threat to preserving and enhancing power and contributing to and guiding this process such as Ahkenaten's intentional promotion with solar Aten.
I don't know about crucifiction. Weren't the tauroctonies bull slaughter scenes? Romans used solar and moon symbologies going back ways before Mithraism was popular. For example see Augustus Prima Porta breastplate that shows Aurora and Luna on each side as the sky-god Caelus rises to the heavens (sound familiar?).
