Why do ,african rock paintings have that euroup and austrain rock panting dont have

Here's a start.
African Rock Paintings have more sharp, more crisp lines. It is easier to establish what they are portraying in their paintings.
On the other hand,
European and Austrian Rock Paintings are more jumbled up, with less crisp and understandable stories.

The Africans used the rock paintings to document their hunt's and keep track.
With European and Austrian rock paintings, they look more crowded with a lot going on. While African rock paintings are very simple.
