Your are of course correct here. I did not formulate clearly enough. I was thinking in terms of modern science. Of course inventions and progress does not happen in a vacuum. Other civilizations made important inventions and made important contributions to the body of knowledge “back then”. The Sumerians were big on astronomy and mathematics, the Egyptians had good knowledge of astronomy, but also of mathematics, the greeks were big on philosophy, natural philosophy and mathematics. Indian mathematicians made important contributions. But the seeds of modern science was kickstarted mainly in (christian) europe, but highly influenced by islamic science (and by extension Indian science, from which it imported important ideas and results) and greek philosophy, mathematics, and natural philosophy. And of course input from the chinese eventually contributed. But these were the foundations on which modern science could build. In the christian sphere, at least some of the scientific work that were done were motivated by a desire to decode “Gods creation”. In any case, speculating how things would have progressed in other cultures and under other belief systems had it not been for the Abrahamic religions will be a matter of counterfactual history.
Actually, the first long and thin edged weapons (i.e. swords) were made of copper. Bronze came later.
The destruction of The Great Library of Baghdad also destroyed a big body of painstakingly built up knowledge.
