For both of you, 702085 and Mega, Shadow's physical age is 50 or 65, canonically he's 15 or 18... remember back in Sonic Adventure 2, where it is said that he had been created 50 years ago on the space station, we all know as Space Colony Ark. In the game a incident had occured, where it led to Maria sending Shadow to Earth and eventually being locked away, not without witnessing her die right in front of him. Eggman's grandfather was arrested and executed thereafter.

It was then revealed in 2005's Shadow the Hedgehog game that he was manufactured by not only Gerald Robotnik, but the Black Arms alien leader Black Doom: thus infering that Shadow is possibly immortal and Black Doom is his first biological surrogate father.

Let's think for a second. Sonic the Hedgehog 06, in Shadow & Silver's story, it gives us a hint on how they are both connected somehow, although not mentioned if the black and red hedgehog fell in love, which could be any Mobian female, but give us incite guess on how Silver could possibly be a son, a sibling, a nephew, a grandson, or simply a descendant. In Sonic & the Black Knight it also hints Silver being related to Shadow, so possibilities are countless.
