Answer 1

Towards the end ofthe war, the nazis were more and more in a hurry, weak and disorganized. Auschmitz was taken during a rapid advance of the Red Army. All the guards who could flee did it, instead of destroying the camp infrastructures.

Not everything was destroyed in Treblinka either, and witnesses were found, as written in Vassily Grossmann notes (look for the book “a writer ar war” from Anthony Beevor)
