"No soy un profeta ni un hombre de la Edad de Piedra, solo un mortal con el potencial de un superhombre. Sigo viviendo."

Simplified Meaning:

This quote means that the speaker doesn't see themselves as someone with magical future-telling abilities or someone from ancient times who had less knowledge. Instead, they believe they are an ordinary person but with the ability to achieve extraordinary things. "Mortal" means they know they are just a human who will eventually die, but "potential of a superman" means they think they can do amazing things if they try hard. Think about a regular person who always wanted to be a great musician. Even if they don't have a natural talent from birth, they can practice every day and get better and better. Over time, they might become as good as the famous musicians we admire. The key is to keep going and keep living life with a positive outlook that they can grow and improve. In life, this means we shouldn't limit ourselves by thinking we're just average. We should recognize our own strengths and work hard to make the most of them. We all have the potential to do something great if we believe in ourselves and stay committed to our goals.
