Archaeologists have found very old rock carvings in the desert of Saudi Arabia. The pictures showed camels, gazelles, and other animals. Experts said the carvings were about 12,000 years old. Some were more than 6 feet (1.8 meters) tall. A report in Nature Communications said this discovery shows that people lived in the area about 2,000 years earlier than was thought before. The carvings were made with simple stone tools that could cut strong lines into the rock. Some pictures were made in high and narrow places, so the artists worked under hard conditions. Experts said the details of the work showed great skill.

A stone tool found under the carvings helped scientists to date the art more clearly. One picture showed an auroch, a type of cattle that is now extinct and did not live in the desert. This finding suggested that the people may have traveled to other places or moved with the seasons. The study also said that people may have used small lakes or rock cracks with water to survive. Experts explained that this discovery is very important because it shows early life, art, and culture in the Middle East.
