I think some reasons that people visit museums are to become familiar with other cultures and histories and to spend their time effectively. Some other people may go visit there them because of their personal interests in history and archeology archaeology and art.
....I don't see a clear difference between the two views.
This can help people realize the differences and similarities between others' cultures and histories and theirs.
... sounds repetitive a bit.
For example, by comparing others' ancient and artistic objectsartifacts with theirs, they can realize the differences and similarities.
... well... artifacts help people understand how those cultures evolved.
For instance, some societies were using and creating the same equipments and devices and weapons in a more advanced way than other ones.
.... I think you can be more specific here. Tell the weapons used by ancient Chinese were different to what have been used by the French in parallel times.
