I've been thinking about this a lot and it's got me curious, because technically their not human, they were made in a lab. They're technically a sentient science project. But given how they have birthdays and how the professor does explicitly states that they'll gain more powers as they get older means they do age. I guess the real question is how human are the powerpuff girls? Are they able to grow old and have families like the rest of us? Or are they just an advanced science project that got way too out of hand?
