There is no actual proof to support the Aryan Invasion Theory.
It was a weakly-invented story created by the British when they
went to conquer India. The reason for the creation of this theory
was to make the native peoples believe that they were inferior and
had to succumb to the British. According to the theory, the Aryans
came from an area north of India.
Recent archaeological activity and many scientific studies have
proven that this theory is false, so don't just take it from
me.
