There never was any aryan invasion. It is fake theory cooked by british missionaries to justify their illegal rule over India and dismiss-enslave-exploit far advanced and superior Bharatiya civilization than any European ones that ever existed. The Aryan invasion theory is dead in research and well-educated scientific community. Shamefully it only exists in our british written indian history text books (carried over by sickulars), for christian missionaries keen to divide Indian society and white imperialists who think Asians and black are inferior. Please don't fall for this aryan invasion bullsht. The people from Indus-valley moved all across middle-eastern regions spreading the trade and traditions. The Indic spread continued all the way upto italy in west and japan in east. The vedic period started at about 7000bc and predates any existing known western cave civilizations. The VATICAn itseft was a Ashram-VATIKA a place were vedic priests once lived. There are idols of brahma found in rome 30 ft below surface dating more than 4000 years BC. Such reports and scientific discoveries are systematically suppressed by missionaries lobbies. A lot of real history of Indic civilisation, kings, clans was forever destroyed when uncivilised Islami jihadis destroyed hindu-buddhist monasteries-temples in Nalanda, Kandahar, Kashmir, pakistan and bangladesh.
We Indians today do not know our history and past. Hence most of our future seems to be in danger and present in big turmoil.
