Just had a look at that source in the OP, it is shockingly bad. It's basically the debunked Gibbonian/Draper-White conflict thesis myths that have no real degree of support among secular scholars any more.
The thesis retains support among some scientists and in the public[1] while historians of science reject the thesis.[2][3][4][5]
Conflict thesis - Wikipedia
The '1000 years of knowledge' is another contender for "most made up fact in history".
It's a bit like this image, sometimes mockingly referred to as "The Chart" because it's so ridiculous.
The Christian Eastern Roman Empire didn't collapse though...
Where do you think the Arabic speakers (it was mostly Persians, etc.) got all of the philosophical texts from which enabled their Golden Age? (hint: Greek speaking Christians, and it was mostly Christians that translated them too)
Although nobody can ever actually name
any of the myriad Medieval scientists who were imprisoned and tortured for their science... Can you?
"Copernicus (1473-1543)21,22, Kepler (1571-1630), Galileo (1564-1642)23,24,25, Newton (1643-1727)26 and Laplace (1749-1827)27 all fought battles against the Church when they published scientific papers that enraged the Church by writing that the Earth might orbit the sun,"
Copernicus dedicated his book to the Pope and his patron was a Bishop. Epic trolling, or....?
" The Ionians discovered the truth about the Sun, the Earth and the stars29, but their era ended when their last great scientist, Hypatia, was attacked by a mob of Christians and burnt in 415CE."
Hypatia was a Neoplatonist philosopher which was as much a religion as it was 'science'. She also wasn't that important a 'scientist', and also was killed during a political dispute rather than because she was a scientist.
Ooh, it actually went there:
"The center of science, the Alexandrian Library, was also burnt and destroyed"
It was perhaps burned by Julius Caesar (and maybe a later Pagan Emperor), although it was never as great a library as is often made out (it was a significant library, but not uniquely so).
Somewhat more importantly, it didn't actually exist by the time the Christians were in charge. So, unless they hated science so much they destroyed a non-existent library just to make sure...
