Are Super Mario Odyssey aka Bowser and jackhammer165 the same person???

Are they the same people?
There have been a few arguments over whether Super Mario Odyssey/Bowser and jackhammer165 are the same people. I was going to make this sorta like the Big Nate/Spyroclub1 trial but that didn't work out so I'm just asking for opinions.

Yes, they are the same person

 * Amerigo Vespucci

No, jackhammer165 is Mario Odyssey's dad

 * Spyroclub1

Agreed they are the same person
why cant they use facebook or something
