Hello, I'm an expert in comic book lore, particularly with DC Comics characters like Superman and Supergirl. Let's dive into the question of who is the oldest between Superman and Supergirl.

Superman, whose real name is Kal-El, was born on the planet Krypton and was sent to Earth as a baby. His first appearance was in Action Comics #1 in 1938. Supergirl, on the other hand, has had several incarnations, but the most well-known version is Kara Zor-El, Superman's cousin, who was also born on Krypton and sent to Earth. Her first appearance was in Action Comics #252 in 1959.

Given these dates, Superman is the older character by two decades. However, if we're talking about their ages within the fictional universe, it's a bit more complex. In most storylines, Supergirl is depicted as being younger than Superman, but the exact age difference can vary depending on the continuity.
