Variations existed in the written form not in the recitation because diacritics (tashkeel) were not standardized. It's a common misconception that the Quran is memorized through the written text. This is not how it is transmitted. Look up Tajweed, which are the rules of pronunciation of the Quran.

Furthermore, memorizers of the Quran can trace the chain of narration back to Muhammad himself. So there couldn't be any forgery or manipulation. Uthman doesn't have the power to erase people's memories.

Since written word is far more reliable than oration, again there is absolutely no proof of any of this.

[jasimq]

In Arabic language different dialects/variations have different punctuations and pronunciations which changes how a word is pronounced but not what the word is or what it means.

I understand this. Spouting random facts doesn't constitute a rebuttal.
