Hi @sandalphon. I think we have similar minds and we like these type of subjects. I enjoy very much your posts. One day I will do more than comment and will write my own articles like you.
Etymology is a beautiful science and I will like to include as a comment my Spanish/Latin background. In Spanish the word for God is "Dios". This word is a direct descendant from the Latin word "Deus" and the Greek word "Theos". Zeus is also related to these words. These words are, at the same time derived from the Sanskrit word "Dyaus", which means sky. Now, gods and goddesses have always existed and the usual is that there is a masculine aspect (the one who seeds) and a feminine (the one who receives). In the case of the ancestral cultures the one who seeds is the father sky and the the one who receives is the mother earth. From there you have the "Dyaus Pitr" of the Vedic pantheon. Now "Dyaus Pitr" sounds very much like "Jupiter" and there is the connection between Zeus and Jupiter.
