What is the difference between Narmer and Menes?

Narmer and Menes are often considered to be the same person in ancient Egyptian history, with Narmer being the name used in contemporary artifacts and Menes being a later Greek designation. Both are credited with unifying Upper and Lower Egypt around 3100 BCE, marking the beginning of the First Dynasty. While Narmer is depicted in the famous Narmer Palette, which showcases his conquest and the unification, Menes is referenced in historical texts as the first pharaoh of a unified Egypt. The distinction mainly lies in the names and cultural interpretations rather than in their historical significance.
