LOL ask a rhetorical question to yourself, nice one bro!
Without Hitler, Europe would be completely different, obviously your need less time on the internet and more time in a Book.
He was making a logical point and you're completely dismissing it.
Think about it like this. We all know that one point in time, some caveman made fire. That's all we have. We don't know the guys name, nor any other accomplishments. Do we have a background on him? No. Did he do something significant? Of course, but that doesn't mean he changed the world.
In Hitlers case, are we going to remember his entire background in a couple thousand years? No, all we'll know is that there was some guy who committed mass genocide. We won't know why, or how he went about it, etc etc. Was it significant? Yes, but that doesn't mean it's changing the world. It's just another significant thing that happened during a time period.
If you think we'll remember Hitler in thousands of years, you're wrong. All of our documentation of him will be gone. Think about all the famous languages that used to be spoken nearly world wide, but now are dead. Latin is a good example of that, so is hieroglyphics. We can't decipher a dead language like that, so we can't figure out what things happened during that time period.
Hitler will just be another person who has does something "talk worthy" per say.
Have fun reading this little essay xD
[EDIT]
hmmm your logic is invalid, i could say europe would be a different place if a cat didnt cross the street at a particaler time in hitlers life and hadnt distracted him so that a car passed him and didnt kill him, i dont know if i worded that right but its pretty much the butterfly effect (no one event has any more signifegance then the next)
That is a great example, +rep
