You have no reason to believe him, he has yet to provide any evidence at all that he has a source ITK. He is just making it up as he goes along.
If he was "just making it up as he goes along", then surely he would have made up an explanation as for why nothing has happened yet, wouldn't he? On the contrary, he doesn't go along at all, but maintains that the information he's provided was correct, in face of evidence to the contrary.
