In 4000 BC Egypt, men and women wore glitter eye shadow made from the crushed shells of beetles.

Ancient Egyptians did use eye cosmetics (kohl) made from minerals like galena and malachite. While they used various natural materials, there's no solid archaeological evidence that beetle shells were specifically used for glitter eye shadow in 4000 BC. They did use beetles (like dung beetles) symbolically in art and jewelry, but not typically crushed for makeup.
