Archaeologist finds oldest rock art in Australia made 28,000 years ago, How come humans evolved to create and enjoy art?

The first statement is a little off in my view, the cave paintings in France and Spain are probably only 37,000 years old. Be that as it may it is safe to guess that cave and overhang art has been in the world longer than 40,000 years but has not been found yet. They have also found paintings of very large birds in Australia that seem to have gone extinct well over 40,000 years ago, so this 28,000 year statement is probably not the oldest. Overhang art found in Africa is in all probability the oldest, but dating of the earliest rock paintings and engravings in Africa is uncertain at best. Direct dating techniques are not advanced enough to accurately indicate an age for them due to their being in the open and subject to the weather and environmental conditions. The art form has to predate the Great Diaspora out of Africa, but it has not been found or overlooked at present. There are some that suggest that Rock painting could be as much as 70,000 years old. Is it possible that genetically we must create art? Look back to your own childhood and seeing animals, ships and even people in the clouds. Is "seeing" images in clouds itself a work of art? The viewer's brain is constructing a representational image out of blobs of water vapor. Is that so different from painting images on a wall or assembling a statue for blobs of clay? What an artist essentially does is take materials paints, in this case and encodes them into a work of art. The later people seeing these decode those works and give meaning to the artists work.
