They communicated through cave paintings. As we know, most painting were depicted to be animals, though there are few paintings that appear to have human etchings in the paintings. Some believe that they wanted to decorate the cave with the animals that they hunted to pay their respects for sustaining their ability to live.

Painting the animals on the cave could also mean that they were documenting their hunting expeditions.
