MUSLIMS IN THE AMERICAS BEFORE COLUMBUS

Re: MUSLIMS IN THE AMERICAS BEFORE COLUMBUS

HOw about you look at Iran? They are an Islamic state as well...whats with Pakistan (after all the political turmoils we have managed to take part in R&D in almost every field). Whats with UAE and the unique infrastructure and fantastic buildings?
Apart of that almost every invention were from Muslims, which were afterwards "copied/stolen" by the Christians and labelled as their invention. Do you feel crying over history manipulated back then?
When we were made to believed that science has had Its birth in Europe? We read hear about the great Gallileos, Da Vincis, Dopplers, Einsteins have you ever read anything on Ibn- Battutas, Ibn-Sinas, Al-Battanis, Al-Kindis,Al-Zarawis at your school/college/Uni?
I havent. I had to read on this on my own.
And then they say Its not about religion and we dont differ between Muslims/Jews/Christians.
