Can we demonstrate that the Quran is perfectly preserved?

I want you guys to prove it to me that the Quran is perfectly preserved. When I say this, I mean I want you to prove it to me that there is an absolute 0% chance that any verse/surah was removed, lost, added or altered since Muhammad (s.a.w.) passed away. I want you to convince me that every single ayah that was revealed to Muhammad is in our Quran today in its perfect form. Use as many sources as you like. They must all be **authentic** and **unambiguous**. And please don't misinterpret my motif for this question. I'm not bashing Islam. I'm just trying to increase my imaan. So please don't take this the wrong way.
