Is this proof of herobrine?

ok, so the server i use (plox), me and a buddy were messing around on minecraft, he was showing me his house, and suddenly a wall of glass appeared, we just broke it and moved on, then all the lights started breaking, a sign reading "brine" appeared... skipping ahead, the "herobrine" created a void, just then, turnerd10 is now online! hes an admin... no other admins were online, no ops either,m then a void appeared, we were really deep underground and hit bedrock, the "ghost" placed a bunch of signs saying tings like "luke showed me the light" and stuff like that, because in our towns graveyard, we have 2 grave, one for a player, another for herobrine, so we didn't fell like pussying out, so we stayed, then the void got bigger... and another sign saying "leave our graves alon" appeared, then we tried to run out, but as we go half way out, boom, stairs disappear, only i died "of course, oh, i died like 5 times so far) then once we Finlay got out, the whole thing turned to lava, skipping ahead again, we sacrificed a pig, nothing happened, we went back to graveyard, and the sign on herobrines headstone was changed, so i change it back, (no, the words on the changed headstone doesn't matter, just rest in peace spelled wrong) and stuff stopped, we went back to graveyard and a sign under the sign on his headstone said "thank you joe" no one on the server has joe in there name, my user name is Benmiralia, its my brothers name, my name is joe... help please, and if it helps, my buddy recorded the whole thing, he will post it on youtube, i will tell you when he does...
