You were asking what contributions Europe has made to science, so here you go:
Complex numbers, Vieta's formulas, Copernicus's and Brahe's discoveries, modern human anatomy in the 16th century. Earth's magnetic field, telescopes, Kepler's laws of planetary motion, Galileo's laws of the falling body, use of logarithms, Snell's law, blood circulation, microscopes, the mercury barometer, the cell, disproving spontaneous generation, the practice of peer-reviewing papers, spectrum of light, calculus, measuring the speed of light and Newton's laws in the 17th century. Taxonomy, Messier objects, Uranus, anaesthesia, modern chemistry (with conservation of mass), the battery, oxygen and extinction as a fact in the 18th century. I'd go on, but once we get into the 19th and especially the 20th century, there are just, frankly, too many to list. You see my point?
So yes, Europe couldn't have made it without contributions from Islam and Central Asia, because Muslims came to the conclusion that God is nature, so by studying God, one studies nature. Christian Europe came to a similar conclusion, except that by studying God's creations, only then would they understand him. So again. Central Asia and Iran had their time in the spotlight. Keyword being had.
So with all this out of the way, I ask you. Where is central Asia now? Especially compared to Europe and the West. Would you really rather live in Iran than the UK? Or Kyrgyzstan than Austria? Because I think I know the answer
