Who discovered three dimensional shapes?

Three-dimensional shapes have been studied and understood for thousands of years, so it's difficult to attribute their discovery to a single individual. Ancient civilizations, including the Egyptians and Greeks, explored 3D shapes in their architecture and art. Notably, mathematicians like Euclid in his work "Elements" laid the groundwork for geometry, which includes the study of three-dimensional forms. Over time, many others have contributed to our understanding of 3D geometry.
