Brahman: The discovery of the God of Abraham

Long before the Aryan Invasion of India, there was indeed a Dravidian and Hebrew Invasion which developed the Indus Valley Civilization. Aryans developed the Vedic religion. However by 600 BCE, Vedism died out and was replaced by Brahminism with Brahman the God of Abraham and the Upanishadic Theology. History added new gods later to produce the religion of Hinduism as it is today.
