Yeah, there's not much to discuss if your assertion is that scientific achievement happens through the grace of god. It's your point of view, whatever, my point of view is that you are a victim of ridiculous propaganda, but don't take it personally, I tend to think the same of any unrelentingly religious people. I'm not an atheist incidentally, just agnostic.
Also I don't understand why some people feel they have to bring everything back to their own origins. It's like some afrocentric historians trying to take credit for the entire history of Egypt just because there were a couple of late Nubian dynasties. The way you're painting this "unification" of Islam is very generous, considering how quickly the caliphates split and warred with each other, and I'm not even going to get into that whole Sunni/Shia schism, which had nothing to do with "pre-islamic racism" as far as I know.
"The Persians and Byzantines existed side by side for ages...but there was no progress until Islam came"
Really? There were no innovations, libraries, scholars or academics of any kind until Islam came? That's kind of exactly what I'm disputing. What proof do you have for this exactly?
"If it was not for Islam, there would be no advanced civilization in Europe or the USA. When the Islamic world was the America of it's time, Europe lived in the Amazon Jungle. One day when the Western world collapses just like the Islamic world, the group that takes over (probably Chinese) will look at us in the West as inferior and backwards because we no longer will have the light of progress that was given to us by God."
And this is really the crux behind your reasonings. You have a massive chip on your shoulder because you believe the West looks down on Islamic countries as backwards savages (not entirely untrue, but idiots are a resource heavily present anywhere humans exist). So you respond in kind. Personally I wouldn't talk about education when you quite clearly believe in some prophesized coming Apocalypse. I wonder how your fellow Islamic brothers feel about your fervent belief in the coming of the Mahdi, by the way... seems like a very specific belief for someone preaching Islamic unity( I know I said I wasn't getting into the Sunni/Shia split, but I lied :3).
Knowledge and "science" is a chain, that Islamic societies were an important link at one point in time wasn't due to an all powerfull deity's will, though of course I can see why you would see it that way. We might as well grant that God apparently favored the Romans for quite some time before them, and the Phoenicians, and the Greeks, and the Persians, and the Medians, and the Assysirans, stretching all the way back to the dawn of civilization, despite the fact that few of them were Abrahamic or even monotheistic faiths. How did God's will play into the rise of the West then? Obviously if we surpassed what was accomplished even in that glorious moment in time when it was all "one nation, one faith, one science" it is because God was with us? Is God with the Chinese now? Was God with the Aztecs, then with the Spanish?
I realize this is a futile conversation since we're approaching it from two completely different points of view. These are interesting historical facts, but I think you're approaching them with a lot of confirmation bias, because they are more a political/religious statement than a historical one for you.
