Well, either people can accept the truth that the reality (and FBI paperwork WHICH can be found on the FBI site) that Hitler, and many other noted Nazi officers set up--with some help from the CIA--a nice little mini-Nazi German community in Argentina called Bariloche. The actual 'death' pic was staged, as he was well aware that he was going to end up beside his officers in Nuremberg, so his ever loyal team--whom were masters of propaganda-- made sure that even though their futures were to be ended dangling from a rope, (save for Goering, whom had soldiers sneak in a cyanide tablet, taking his own life.)

Why? Many reasons. Despite the Nazi reality of genocide, and all that jazz, there were many, MANY technological advances that were too important to throw away, especially the scientists, engineers, and doctors that, for all intent and purposes, were quite advanced in many fields that were too important to throw away. Ironic that this arises, now, especially seeing Nazi technology at work with the newest innovation of a 'Flying saucer', was based on actual blueprints and a slight unfinished product that has been being eyed by NASA--now a reality.

As for the way he looks, (yeah, even his ears) If you have forgotten that our features change when we age, and also knowing that many of the Argentinian community were well adept at facial reconstruction, even if it was just enough to change a slight recognition.

And yes, you better believe that The Vatican were involved...
