I find your question only somewhat interesting. On that note, I think it would be best to remember that some form of "religious rituals" were older than the actual development of language. Yes, cultured individual speaking is a language, but only recognized within their own culture. Language did not expand or grow, until more and more people became conscious. As more people became conscious, the only reason most language has "god" in or predicated on there being a god is because people prayed to some form of higher power, long before, therefore it was included.
When doing the research of World History and Religious History, I found that most languages relied on religious words, so as to speak and write. Then again, at the time of the development of language, religion was primary versus anything else at the time.
