Archaeological excavations of prehistoric peoples have found cave art and skulls that indicate what type of treatment was used for mental illness at that time?

Trephination

Explanation:

The cave art and skulls found by archaeologists most likely indicated a treatment known as Trephination. This is the process of surgical procedure used by ancient civilizations where a hole was either drilled or scraped into the skull by using very simple and basic surgical tools, in order to either treat mental illness or release blood buildup caused by an accident.

i would think yes.

explanation:

because we have every natianlity in our country which makes us so diverse and unique. that's why in a lot of cities there are places like little italy, koreatown, chinatown.  

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
