MUSIC

WHY WILL IT BE DIFFICULT TO KNOW WHAT KINDS OF MUSIC THE EARLIEST HUMANS MADE?
1. Early humans most likely did not make any music.
2. Much was made using the body, leaving behind no evidence.
3. The kind of music made likely varied according to culture.
4. Instruments have been found, but we do not know who to play them.

All of the options provided contribute to the difficulty in knowing what kinds of music the earliest humans made. However, option 2, "Much was made using the body, leaving behind no evidence," fits most directly with the question. This is because early humans likely made music through methods such as clapping, stomping, or vocalizing, which do not leave behind physical artifacts or evidence for us to study today.
