How did the discovery of the cave paintings at altamira change perceptions of ancient cultures?

Linguistic, anthropological and archaeological studies affirm that our ancestors bequeathed us their first ideas and impressions about writing, through pictorial manifestations that were a way of seeing and understanding the world.

Cave paintings, therefore, directly express a meaning without intervening a linguistic form.

Many studies have shown that a story can be told through images, since they can carry most messages with them effectively.

an example of the above, we find it in the pictorial writing that the American Indians used with enough familiarity and practice, to communicate their knowledge through a specific message.

From all this we can conclude that the cave paintings taught us how to communicate in a more specific and clear way what changed our perception of the communities of prehistory in terms of their form of communication.
