Bloody u guys are poor in history that's all. * Where was the first univarsity on earth? * who gave the "0" to the world? * who conducted the surgery in the early history? * Who was the master of economics centuries back? etc etc.
We are today cleaning toilet in gulf only coz external forces attacked ruled for few centuries and ruined us.
Moghals were the first culprits, then the brits.
Even today there are so many sanskrit scintific works at Europe library rottening!!!.
So learn something from history along with ur bible.
