It was widespread -this knowledge- yes. The justification part I wrote about was regarding the two parties in this debate, not that one. As should have been clearer by what I said post that sentence.
Nonetheless on a wider issue, I've heard and read of the books that were burnt due to the Quran etc, but they, the Muslims of that bygone era were the bridge between this world and the one you are referring to. You cannot deny them that?
Because your argument is that knowledge transferred hands. They selected the right one in that book; so there is no debunking on that issue, if you agree to that interpretation of course, and I see no absolute reason why you have to agree to that interpretation; it is for the believer. It's all poetry, and exacting science being extracted out of that material has always been more helpful to the Muslim than the critic in my point of view.
Nonetheless, they, as a culture and society of that time did a great deal of good work, by looking and searching for knowledge, and translating a ton of work, that could so easily have been lost from this world. Give credit where it is due. Regardless of whether they were muslim or not, or that they did is because of a book or not, or whether they were muslim in name only or whatever, the fact remains we owe a lot to those interpreters and seekers of knowledge.
And in my view it doesn't do well, to blacken history, so as to prove that ALL religion is bogus; let's laugh at that ignorant lot in the dark ages, he he. Just debunk what has been put in front of you, and you seem intellectually able to do so.
From the op to here, it's all a big massive trolling effort. It's so tiresome having to do this again, and again, again.
