Is Adolf Hitler still alive?

There is a popular belief that Adolf Hitler was still alive at the end of the war and has left out Berlin. And the troops who captured the Reichstag has found his dead double. Let's see can this version be true :)

Versions of survival:

1. Hitler has escaped to Argentina where he hid until the 70s. Then he moved to the Third Reich secret base in Antarctica. Where he can still hiding.
2. Hitler was an occultist and interested in different secret sciences. So, he could teleport, change his body etc.
3. There is the logical solution would to step back when you lose the battle. So, he did it and left his double that nobody will seek him after.

Versions in opposition:

1. Doctors confirmed that there was the true body of Hitler. Officially, it is no doubt.
2. Hitler was already very sick and going crazy at that time. He could not stand by himself and was almost blind.
3. Adolf did not see the future without the victory of the Third Reich. He knew that he would have never won this war if they gave the capital. So, he decided to stay until the end despite his generals advices to escape.
4. If there wasn't 100% probability that Hitler isn't dead, Stalin was searching for him till the end of time. Just like the Jews, who have sought and brought to justice even the most ordinary escaped soldiers of the Third Reich for decades.

All versions of his survival are not more than a hog-wash or the story for a sci-fi movie. Hitler was very sick, did not wanted to retreat and had made too many enemies to escape without harassment. Is Adolf Hitler was or still alive? Absolutely not :)
