What you wrote was “I find it very interesting that a person can get a pilots license at 12 years of age...”. This is simply not true, a 12 year old can fly a plane (with a CFI at the other set of controls), but a child must be 16 before they can solo, and they would have to be licensed (17 years old) before they would be allowed to solo across the country.
I changed it later. Read all my comments please.
