I don't know the answers to your questions, though I do have knowledge of his childhood. He showed various abilities that were superhuman. When be became an adult, he adopted the Superman persona to help humanity.
I know right, Superman is amazing, I couldn't imagine his childhood and him realizing he has superhuman abilities
