Why is it problematic for historians to use oversimplifications when writing about the past?

It is in fact problematic for historians to use Oversimplifications even writing about the past because Oversimplifications often ignore complex or contradictory evidence.

because its important to learn about other countries and how high tech they are compared to us. also its good to learn about other cultures and how ours differs and in common also we need to learn about companies that we still buy since they ship it here.
