At what temperature does DNA become unusable for identifying people?
Dead people I mean. Like what temperature would a corpse have to be
burnt at for them to be completely unidentifiable
REALLY long .....

Very strange question...
For the DNA to be completely destroyed (covalent bonds broken), a
temperature of at least 400C would be required.
I arrived at the temperature by using the info on this page. The
temperature provided is more of an approximation than anything else.

On a side note, if you leave the corpse alone for long enough, the DNA
will be naturally decomposed.
Greetings, 911_researcher!
As I am fond of reading about forensic pathology, I want to mention
that I have read that when a human has been dead for decades or even
centuries, or when a body has been reduced mostly to crumbling bone
and ash due to a conflagration of extremely high temperatures, in
certain exceptional circumstances scientists have still been able to
extract viable DNA from the pulp deep in a surviving tooth.
I hope that you find this information helpful.
