Bible Teach book says:
17 The Bible shows that all the many forms of false religion are part of "Babylon the Great." (Revelation 17:5) That name calls to mind the ancient city of Babylon, where false religion started up after the Flood of Noah’s day. Many teachings and practices now common in false religion originated long ago in Babylon. For example, the Babylonians worshiped trinities, or triads, of gods. Today, the central doctrine of many religions is the Trinity. But the Bible clearly teaches that there is only one true God, Jehovah, and that Jesus Christ is his Son. (John 17:3) The Babylonians also believed that humans have an immortal soul that survives the body after death and can suffer in a place of torment. Today, belief in the immortal soul or spirit that can suffer in hellfire is taught by most religions. (Bible Teach chap.15 p.152 par 17)
Can these practices be traced to any other place (post "flood")?
