A man in futuristic attire stood before the scientists, `` We were responsible for Hitler's rise to power... ``

 `` In order to cause the war that would lead to the dictocomy of the Soviet Union and United States we had to do it. Without the space program from that conflict science would advance in marvelous ways, but, not into space... our version of Earth is days from being destroyed by an Asteroid.'' 
 
 `` Wait... you can alter time but not stop an asteroid? ``, the scientist asked with a biting a tone. 
 
 `` We lack the infrastructure to develop a solution in time, advanced or not... that does n't appear overnight... We had made the earth a paradise, yet, we were inwardly focused.'' 
 
 `` Why could n't you just tell us this?... `` 
 
 `` Would you have believed me? Enough of you? Your space program is in its infancy, but, you now have a chance at survival. We must go and face our destruction in our own reality.''
