In his book Moisés y los Extraterrestres, Mexican author Tomás Doreste states,
Voltaire was of the opinion that Abraham descended from some of the numerous Brahman priests who left India to spread their teachings throughout the world; and in support of his thesis he presented the following elements: the similarity of names and the fact that the city of Ur, land of the patriarchs, was near the border of Persia, the road to India, where that Brahman had been born.
The name of Brahma was highly respected in India, and his influence spread throughout Persia as far as the lands bathed by the rivers Euphrates and Tigris. The Persians adopted Brahma and made him their own. Later they would say that the God arrived from Bactria, a mountainous region situated midway on the road to India. (pp. 46-47.)
Bactria (a region of ancient Afghanistan) was the locality of a prototypical Jewish nation called Juhuda or Jaguda, also called Ur-Jaguda. Ur meant "place or town." Therefore, the bible was correct in stating that Abraham came from "Ur of the Chaldeans." "Chaldean," more correctly Kaul-Deva (Holy Kauls), was not the name of a specific ethnicity but the title of an ancient Hindu Brahmanical priestly caste who lived in what are now Afghanistan, Pakistan, and the
Indian state of Kashmir.
"The tribe of Ioud or the Brahmin Abraham, was expelled from or left the Maturea of the kingdom of Oude in India and, settling in Goshen, or the house of the Sun or Heliopolis in Egypt, gave it the name of the place which they had left in India, Maturea." (Anacalypsis; Vol. I, p. 405.)
"He was of the religion or sect of Persia, and of Melchizedek."(Vol. I, p. 364.)
"The Persians also claim Ibrahim, i.e. Abraham, for their founder, as well as the Jews. Thus we see that according to all ancient history the Persians, the Jews, and the Arabians are descendants of Abraham.(p.85) ...We are told that Terah, the father of Abraham, originally came from an Eastern country called Ur, of the Chaldees or Culdees, to dwell in a district called Mesopotamia. Some time after he had dwelt there, Abraham,
or Abram, or Brahma, and his wife Sara or Sarai, or Sara-iswati, left their father's family and came into Canaan. The identity of Abraham and Sara with Brahma and Saraiswati was first pointed out by the Jesuit missionaries."(Vol. I; p. 387.)
