I think there is no way, except he himself appears and does all the verifications of the reactions, the origin of bitcoin. A lot of rumored information about Craig Wright is Satoshi but it is not validated for any Court or any vote 
lol
Satoshi Nakamoto indeed can't be found unless he shows up and reveals who he is, I did not believe with Craig Wright because he claimed that he was Satoshi who created Bitcoin. it is information or FUD news about CW because there is no strong evidence if he is Satoshi. lolI don't think he wants to reveal himself to the public because I am sure after he reveals himself, many people or governments will trying to search more about him. That will be too risky for him because that is related to his safety and his family too will be at the risky situations. It is better we let him stay in the dark, and if he decides to reveal himself, I am sure he will make some preparations, and he will make sure that he and his family will be in the safe places.
