Hello Spiritlead,
Brother AabiruSabeel has already covered the main points, but I thought I'd throw in a post as well for good measure.
In your posts I see you've been basing your points on speculation rather than factual information, which is quite disappointing and suggests you're not really interested in an honest discussion. If that's the case then I doubt any of us will waste time in providing further responses.
A number of Companions memorised the Qur'an during the lifetime of the Prophet صلى الله عليه وسلم including the four rightly-guided Caliphs (Abu Bakr, ʻUmar, ʻUthman, and ʻAli), ʻAbd Ar-Rahmaan ibn ʻAwf, Az-Zubayr ibn Al-ʻAwwaam, Muʻaath ibn Jabal, Ubayy ibn Kaʻb, Zayd ibn Thaabit, Abu Zayd, ʻAbdullaah ibn ʻAmr, and others
. So to say they
'simply memorise Uthmans Qur'an' is a very poor understanding of this topic and doesn't even make sense considering we have an exact record of the Qur'an via numerous chains of transmission going directly back to the Prophet صلى الله عليه وسلم via multiple Companions.
Another key detail is that the action of Uthman رضي الله عنه was agreed upon by all of the Companions. Had any change occurred to the Qur'an, there would have been numerous people to object, but instead they approved of what occurred. In particular, the Companion Zayd ibn Thabit رضي الله عنه was a part of both committees assigned to the task of compiling the Mushaf at the time of Abubakr as well as Uthman, and Zayd himself witnessed the last recitation of the Prophet صلى الله عليه وسلم to Jibreel. He was also the primary scribe of the Prophet صلى الله عليه وسلم and had memorised the entire Qur'an during the lifetime of the Prophet صلى الله عليه وسلم. Any potential mistake or change in the compilation of the Qur'an would have been detected by him.
These are just a few reasons why it is inconceivable that the Qur'an we recite today is in any way different to what was recited by the Prophet صلى الله عليه وسلم to the angel Jibreel in the final year. This is a point which is clear to any unbiased researcher, whether Muslim or not.
Firstly, to say that the San'a fragments are the 'oldest' is questionable because several dozen first-century manuscripts of the Qur'an exist in various libraries around the world. Secondly, the existence of minor differences in the text of the earliest masahif (manuscripts) is no surprise to Muslims familiar with the history of the compilation of the Qur'an. Such variations could be due to several reasons. For instance, the Companions initially had their own personal copies of the Qur'an which were not complete, authoritative copies. These were for personal use and as such the Companions could have written any knowledge besides the Qur'an such as interpretative clauses, prayers (du'as) etc. Another reason relates to the spelling of words. Interestingly, Dr. Puin who was associated with the restoration of the Qur'anic fragments in San'a, wrote a letter which was quoted in the Yemeni newspaper
Ath-Thawra, in which he said:
'The important thing, thank God, is that these Yemeni Qur’anic fragments do not differ from those found in museums and libraries elsewhere, with the exception of details that do not touch the Qur’an itself, but are rather differences in the way words are spelled. This phenomenon is well-known, even in the Qur’an published in Cairo in which is written...'
At the end of the day, the primary way in which the Qur'an has been transmitted from generation to generation is orally. The presence of the teachers alongside each official copy, the ubiquitous recitation and memorization amongst Muslims and the countless other copies available for cross checking are reasons why even the slightest scribal error is immediately and outright rejected by the Muslim populace. It would only be a case in point if an error had gone unnoticed and resulted in a variant text amongst Muslims. But Muslims have forever been united on one text free of variants and even the slightest mistake could be recognised and rejected even by a child.
This is mere speculation and goes against factual information. Again, the points I highlighted above are enough to show that the Qur'an has been preserved throughout all ages and disputes.

If you apply the same level of criticism to the Bible that you've been applying to the Qur'an, you will be forced to conclude that it is far from being 'highly reliable'. For instance, on the one hand we know that the entire Qur'an was revealed and memorised during the lifetime of the Prophet صلى الله عليه وسلم, such that it could be passed on to subsequent generations without alteration. On the other hand, the Bible was not complete until several decades after Jesus عليه السلام left this world. We also have the issue of different versions of the Bible each containing different numbers of books and many other issues which have been discussed numerous times before. Below is a list of threads where you can find some of them.
