Are you equating ID with Christianity? ID is just as compatible with Islam as it is with Christianity.
When Saudi Arabia or Afghanistan had "things like science" and when did they replace them?
Islam was a major supporter of scientific endeavors in the Middle Ages, especially astronomy and mathematics. We don't write with Roman numerals, we use Arabic numerals. The use of the digit "0" came from them (write "zero" in Roman numerals). The very name of Algebra comes from "al-jabr", an Arabic phrase.
How come that science itself was CREATED by the Roman Catholic Church in the Middle Ages?
You can't be serious. You actually believe that the scientific method was developed by the RCC?
Oh, yeah, and there's also a good reason why the names of almost all of those stars known to the ancients have Arabic names.
Well, that's a stretch, I admit. I would say that the scholastics of the 12th and 13th centuries laid the philosophical groundwork that led to the development of the scientific method.
I did not talk specifically about scientific method, but yes, scientific method was developed in the Middle Ages using scholastic concepts - it is in History of Philosophy 101 :). Science with the whole organizations and rules was created by the Roman Catholic Church.
This is not a belief, this is a fact. But using the scientific method is not enough to be part of science. You need to get your work be reviewed, approved and published by the recognized in the recognized official channels. Then it becomes the integral part of the body of science. Contradictory claims/theories have to be compared and debated in proper formal manner as the scientific knowledge is believed to be universal, objective and binding all, same way the details of Catholic doctrine.
Science is a living integrated organized and visible institution which branched out from the organization and practice of medieval Roman Catholic Church.
It is true that some scientific concepts you can find in ancient times or in cultures on other continents, yet at most this alternative scientific practice took form of secret societies like Pythagoreans, some Hindu or Buddhist monastic orders. In less organized forms there were private schools centered around gifted teacher like Platonic academy. Or you had the continues body of knowledge fused with the religion like in Egyptian priestly cast.
Then you could find some little organization in transfer of crafts/trade methods withing families or workshops. This is not science either.
Still you can find the interesting remains of science origin - ceremonial dress, some quaint rules like celibacy for scholars long after Middle Ages passed, (Oxford and Cambridge scholars well until XIX century), the key titles like PhD - Doctor of Philosophy derive straight from Medieval times (why the doctor of Chemistry is called a doctor of philosophy?), and much more.
