And it took how many hundred years for all that to come about and bear fruit...literally? Not sure what motivates you to rewrite several hundred years of established history but whatever.
For your simplistic mind, the question is not what happened but what would have happened without scientific growth and discovery. It is demonstrably provable that economic conditions, scientific discoveries, and even medical science advanced from 600 to 1300 A.D. Moreover, these advances took place in Europe FASTER than anywhere else in the world (Lateen sails, eyeglasses, clock technology, cannon development). Now if you're going to be so dense as to argue this, at least TRY to inform yourself first by consulting some of the sources I gave you. Here are more: Joel Mokyr, "The Lever of Riches," or Pernoud, "Those Terrible Dark Ages: Debunking the Myths," or Peter Wells, "Barbarians to Angels."
This is global warmism you are peddling. Please stop.
