Even within Europe, there was significant scientific progress during said dark ages. It's extremely obvious by just looking at a 9th century building to those from the 14th century (especially churches). The latter require profund knowledge of mathematics/civil engineering. We went from tiny windows in 2m thick brick walls to vast, airy Gothic cathedrals (although those did take a couple of centuries to actually finish).

Although to be fair, that knowledge did largely come to Europe from the scholars of the Arabic world.

Only thing I, as a European, know about MLK is that "I have a dream" speech and that he has something to do with rights for black people in America. My memory stops there.

Funny enough, in Catholic religion class I learned more interesting things about history than in history class itself. My teacher made sure we knew about other religions, how all of them are connected, how they developed, what some did while others went crusading, etc. Best teacher I’ve ever had.

To add to it. A lot of the European antique that the West loves to pride itself in, such as the work of Roman and Greek philosophers and scientists were only preserved by the Muslims in the Middle East and subsequently rediscovered from Arabic and Persian works. So a lot of European culture and history was preserved by outsiders as the white barbarians couldn't hack it. Unlike the imperial museums in the UK, France, Germany or other countries, that preservation was achieved largely without pillaging.

Dark ages didn't happen is the issue with your point. There were many new technologies developed and progress being made.
