the Indus VAlley civilzation's latest excavations in Porkistan by Porkis is saying that it existed around 3300 B.C. which means now around 5300 years ago -
now use UR common sense if 5300 years ago these people could build well planned cities which have never been found anywhere else in the world then how could they have migrated from somewhere else? If they did - such cities should be found around those places as well -
Every historian today agrees that the ROMANS MAnaged to build such cities only after about 2000 years from this civilization ?
IF we go with even 5300 years ago - the kind of cities build clearly shows their technological Knowledge - it means MR Tamilban the CULTURE and History of this country is much much older then U can imagine even in UR Dreams
These people wouldn't have got up one day and build a city - it would have taken centuries for them to arrive at such knowledge
