We also know, that this was the scene of a monster storm system. For example, who is to say that the VS and other pieces of debris were not sucked up by waterspouts and deposited at the site where they were discovered a few days later.
But the main argument has to be that a well-funded well-equipped year-long search operation came up with no evidence of the aircraft's presence (debris, signals from the pingers, etc.,) beyond what was discovered in the immediate aftermath of the event.
