I just read first few lines but the article mentioned about Indus Valley Civilization that it got wiped out 4200 years ago.

That's incorrect because as an Indian we are taught about Indus Valley Civilization and it existed 3300 BC to 1300 BC Which means it was there 5300 to 3300 years from now.

So I quickly lost interest. I mean just say your point, why you have to be factually incorrect in trying to make your point more significant than it actually is.
