A is not true. There have been many studies on eye witness testimony that disprove everything your saying. The reality is that our brain fills in many, many gaps.

B, you completely missed the point. Just completely missed the point to read that sentence the way you wanted to, "many of the details are completely meaningless to the premise that is presented" has nothing to do with memory. That's why it starts with "Even if we believed someone could have a memory this crystal clear...." So why are you even bothering to argue about memory with me when I gave the memory the benefit of the doubt in my argument?
