The option that could be a reason why humans know very little about the time before the ancient era is that no historians have written about the era that preceded the ancient era.
We are referring to what is cold prehistory, the time where events occurred before the existence of written records.

There is supposed to be answer choices for this particular question. The clash that the American rebels succeeded in conquering the British troops was the Battle of Lexington. The Minutemen at Lexington ambushed the British troops and prevented them from proceeding to Concord to confiscate the patriots' supplies. If the choices were here, the correct answer would be B.
