well, the Allies knew about the research on nuclear weapons done by the Germans, and I would think it's not like they left the potential escape to the very last minute.. accessing that info in 1943 or 1944 would have been of vital importance for the race to nuclear weapons.
I'm not saying I believe it all of course, but I wouldn't even rule it out completely. The fact still remains that there is nothing that proves that what they found were the rests of Hitler and Eva Braun. The modern forensic evidence gathered by FBI experts seems to tell that the skull bits found do not belong to a man in his late 50s. I am pretty confident that finding a body with a bullet wound to the head wouldn't have been a hard task to accomplish in Berlin in 1945.
As for the witnesses that reported the facts: if they were devoted enough to spend their last days in a bunker with Hitler, I really don't see why the few of them could have as well decided to do their ultimate act of faith and
lie about Hitler's fate.
In any case, I do not understand on which basis you lot think this couldn't be even remotely possible.
