This is the video of fake herobrine

Herobrine is not in Minecraft.
By Tarek Almustafa.
There are no references to him at all in the source code,and there is no code to allow for any entity to act like herobrine.There is no level terrain code to generate redstone torches, 2×2 tunnels or elaborate dungeons with traps.
There is no possible way herobrine can ever exist in any unmodded
clients or servers.
The End
