Answer:
Surprisingly, both!
Explanation:
You're probably looking for me to pick one, but I believe that history is shaped by Both great people and economic, political, environmental, etc. Here's some examples.
Historic moments (Shaped by people) such as:
* Newton and gravity
* Greek Mathematicians
* The invention of the light bulb
And so much more.
Historic moments (shaped by economic, political, environmental, etc.) such as:
* America's Independence
* World war I & II
* The industrial age in general
These are just a few examples of how both shape history. It kind of like a lock and key. Can't have one without the other. ;)
Hope I've helped.
