Aehh Mr.logic.Just google about India's history.You will get answer.India created its own civilization.It is correct ,foreign invasion happens in our history .And our culture and language absorbs some parts of invading culture .But still we follow that basic Indian culture and religion even if there is some slightest change it is still indigenous.
You may boast and claim that your culture is similar to that barabarian invaders.But our civilization is created us by our own hardwork.So we dont believe in AIT bullshit.
Ok all right, lets end this debate.
