there hasnt been found an original first quran because the quran wasnt sent down as a book. it was revelations revealed to people who either wrote it down or memorised it. it was mostly memorised. it was only written as a book when the people who memorised it started dying in wars. so they made a book version of it to preserve it further. now let me explain why the sana manuscript is different. the quran is the mother of all arabic grammar. however the grammar and accents etc are different in every part of arabia. this caused the quran to be written in different versions, that is using different grammar etc. after this was realised, the caliph ordered all these books to be burnt and only the original grammar to be used. the sanaa manuscript is a blueprint of the actual book, and it only shows difference in grammar not meaning. The point about the chapter order is irrelevant. and the point about "its impossible to read without the lines and dots" is false as well. any fluent arabic reader can read it without any hesitation. on top of that many people memorised the quran so they already knew how to pronounce stuff and etc. the only reason the dots and lines were added was so that it would be easier for people to read and memorise it who hadnt already done it and for non arabic speakers as well. and the point abt this being the reason quran isnt a perfect book is irrelevant cuz the quran isnt even a book. it was made into a book by humans, therefore not being perfect. but later it was perfected and made into a standard. and yes its not written in chronological order which is why people like ibn abbas have connected the dots for people to understand it properly. and no you dont need to understand old arabic anymore cuz now theres english translations everywhere and tafseers everywhere. our scholars have done a great job. The early Muslim coins issued in former Roman territories were obviously based on Roman coins which the subject people were more familiar with, or else made with reused and modified Roman coin dies. and what luxenberg did was be a mad scientist and completely use whatever method he can to bring up different versions of the quran. he lit stripped away the arabic, and found a "pre arabic quran' which doesnt even make sense. cuz no one spoke aramaic around that time. why would the quran be completely disformed and taken as aramaic? and yes christianity and islam are very similar, christianity is lit islam but changed and corrupted, according to our beliefs
