No one can tell u that with proof. But, as far as Bitcoin is concerned, it does not matter who is Satoshi.
Exactly, there's really no need trying to know who Satoshi is, it is in everyone's best interest that he stays anonymous, if the identity of Satoshi is known, he will have a lot of questions to answer, even the government will not let him be, he may have even be arrested as fraudulent and trying to cause damage to the economy.
