Are paintings text and technology?

Evolution implies that humanity evolved from low intelligence to intelligent beings. The authors of the sites insist that Paleolithic humans were by no means stupid. If they were, then stronger and more vicious creatures would have vanquished them. To survive, they would have to have used their reason. The paintings convey the reason and reflective traits of these ancestors.
What do the paintings mean? Are they text or technology? I argue that they are both.
The paintings are clearly part of technology. The cavemen needed to find something with which to paint the wall (Chauyet). Of course, the substance would have to stay on the wall, dry quickly and not drip. From the Chauyet site, they even developed such innovations as shading and perspective. On the Lascaux site, in the main Gallery, there is evidence that the painters used geometric shapes, and employed methods to create 3-dimensional images. It reminds me of the Renaissance artists using geometry and every method they could to produce 3-dimensional masterpieces.
The paintings are clearly text. The cavemen used the technology to convey meaning. In all three sites there are paintings of much game, some of the animals now extinct, such as large wild oxen and wooly mammoths, but either the painter was expressing the meaning of prosperity or wishful thinking. Key is the use of methods to bring out the illusion of movement. In the Painted Gallery (Lascaux), one sees “Chinese” horses expressing movement and grace. A large black cow seems to be falling, or as I see it, leaping over an obstacle. Also, the painters have brought out conflict, as shown by two opposing ibexes.
The paintings show hunting. Not all ventures were successful, as shown in the Scene of the Dead Man (Lascaux), wherein the bison bests, or rather, gores, the would-be hunter. The anger of the bison is brought out in the painting.
The paintings can express a religious theme, though for Dr. Kamat, it is mostly of gloom and desperate searches for protection in the paintings at the Indian cave. Still the idea of religion indicates some level of abstraction, that there is a power above them.
A possibility of another religious theme is indicated by the painting of a unicorn (Lascaux). Having seen so many unicorns in New Age propaganda, I was surprised to see it on a cave painting. It is unlikely that such beasts existed, but if not, whence came the concept? It would be more evidence of the Paleolithic ability to make abstractions.
Another way of this ancient form of text expressing meaning is though a possible sense of humor. In the Lascaux cave, there is a scene in which a bull, an herbivore, has long eaten a bear, an omnivore. Such an event does not occur by nature, and the people in that age were very practical, as sheer survival would force them to be, thus, if it is humor, then it is another example of abstract thinking.
Text, ten, does not have to be writing. These paintings speak many words across the millennia.
