An "Out of India Theory" is proposed by some scholars, (e.g. S.S. Misra, David Frawley).. Based mainly on archaeological evidence and references in Hindu texts, the Out of India theory proposes the idea of the Indo-European languages originating in India. However, some linguists do not consider South Asia a serious candidate for Proto-Indo-European origin, though some astronomers differ citing Hindu texts and analyzing star patterns , eclipses, and the like to justify OIT and the historicity of Hindu texts.
