Consider the innovation of the internet. Is it the greatest creation in mankind’s history? Is there something that has changed the world more?

You could say yes and no

Explanation:

Every change that has gone into practice successfully has changed the world in its own way. Yes the interent is among one of the most recognised but we would not have reached that point without civilisation prospering in the way it has done. You can't expect the beginning of the world to just come up with something as graet as the interenet. It has to have reached that point. I would say evoloution has changed the world in the greatest way. But then again evoloution is not an innovation. Because of this we are able to come up with all these amazing things so this question is debatable but this is my answer.

Hope this has given you some idea of your own beliefs. :)
