Christians (and Muslims), do you believe that the bible (or quran) is the only source of morality?

i believe morality is a trait evolved over time as we possess great intelligence to incorporate it into our society. Bible to me is a book that preaches about those morality, but no, it is not the only source of morality, any book that teaches about no stealing, no cheating, no lying are all other sources of morality, and some of those books, such as the ones in China, are older than the Bible.
