I see so many theories about the death of Hitler and the possibility he had not died, but I never saw any evidence that he has died or even that he survived.
Well for one thing we have several eyewitness accounts of people present in the bunker at the time of Hitler's and Eva Braun's suicide. For example Traudl Junge (Hitler's secretary) and Otto Günsche (Hitlers personal adjutant). Günsche was tasked by Hitler with ensuring the cremation of the bodies after their deaths. He made sure the bodies were cremated before being captured. There are more eyewitnesses, but these are the two I could remember. And I'd say they're pretty reliable.
