Saying that is "pure speculation" is a bit of a stretch.

1) Martin is Spider-Man.

2) He looked like Peter Parker in his youth. And his wife looked like Mary Jane Watson.

3) He lost a person named Ben Parker. His origin is pretty much like Peter Parker, because of that.

4) Nick Fury helped him have new identities, hence why he's named Martin.

5) Every mix up is a consequence of his memory, as hinted when Stephen corrects him the name of Kraven the Rhino.
