I was there for that stream. I'm genuinely surprised how well you remembered what it actually looked like, as I had totally forgotten up until now. I am friends with cope and even he has pretty definitively said he doesn't think anyone will ever find it. Once livestream ended, I'm pretty sure the actual stream disappeared then and there. It's not like they could really save every single stream clip/recording. pretty confident it's truly lost. I would love to see it again though, just for the nostalgia lol. Another reason I think it never got saved is no one really knew how much of a legend it would become, so no one really bothered to save the clip from livestream.
This is incorrect information as me and a few others clearly remembered the livestream being linked on the Minecraft wiki's Herobrine article at one point. So it was definitely around for a while. Anyway the full stream has finally been found now!
anything before 2012 was lost/hidden caused by cern when it created all the alternate realities we are currently shifting through. this is why minecraft seems so weird and diffrent now. like we know its minecraft but somthings not quite right..somthings off by a tiny bit. makes the hair on your skin stand up. but we will never know where herorbrine may have went
