Shadow Player

Hi guys my friends have found a weird glitch that is similar to the Herobrine myth.
The actions of this entity are-
Setting buildings on fire
Stealing items
Killing animals and players
Building
Mining
Luring monsters to us

We have only found this on Xbox but here are some proof videos
