It wasn't created by Jor-El but was found by him in the caves on Earth after he saw the Kents. He took it to his lab and improved it but sent it back to earth for his son to find before he was forced to turn it into a weapon. Turning Krypton into a police state. He improved as a care package for Kryptonian's. Dating its creation back to a century before Krypton's first generation. Clark has Emil Hamilton research and tap into the box.
