 The reason that earlier Western scholars believed them to be of a later origin is due to the monist views found there.They believed that early Vedic religion was pantheistic and a monist view of god evolved later in the Upanisads - but the poems of Dirghtamas (1.164.46) which say "there is One Being (Ekam Sat) which is called by many names" proves this idea incorrect.Some scholars have claimed that the Babylonians invented the zodiac of 360 degrees around 700 BCE, perhaps even earlier.
