Historians affect history because the bias of historians will affect the way that they record events.
Whether intentional or unintentional, many historians include bias in their writing when recording events. Bias is your personal beliefs or attitudes skewed for or against a topic that influence your writing. If a historian includes this in their writing about an event, it can change the way that the event is perceived by the public. Many historians relay the facts in a similar manner, but it is the bias that makes their stories unique from one another and also how they affect history.
Hope this helps!
