I think I found an explanation as to where some of the rumours regarding Herobrine came from.

Supposedly, in earlier versions of Minecraft, under certain conditions, it was possible for an additional player to spawn-Though it wasn't able to actually DO anything-It was some kind of data error. Not only that, eventually, it would disappear, as if it had the ability to teleport! This bug was actually reported later on as well, as late as 2013: https://bugs.mojang.com/browse/MC-37586 (Really, this was just due to the game lagging out on rendering that you logged out, and logged back in:It vanished when the game finally got rid of this extraneous clone-But it looks indistinguishable from Herobrine's "teleporting") Hm.. Wonder what would happen if I interacted with this glitch clone? Would the game crash..? Maybe.

This is, of course, due to a bug with servers logging in and out-Though something similar may be possible in single player, if the game lags too much:An item duplication glitch from something similar (In this case, entering and exiting the Nether) was actually proven to have once been possible in 2010, the very year that "Herobrine" started being talked about, before being fixed:https://www.youtube.com/watch?v=2JyJUH987EA (But no extra player here-Though it DOES prove that some kind of item duplication is possible through logging in and out.)

There was also a bug report of certain entities (though not players) duplicating in 2012:https://bugs.mojang.com/browse/MC-22147

This proves that at least entity duplication was likely a thing-In single player no less;so there may have indeed been a way to get a Steve to spawn in your world-Looking almost exactly like Herobrine (Steve was the only default skin until 2012, when the first pack was released-And you could only modify your current skin starting December 2010-So before then, Steve was almost always going to be your skin-And the earliest post about Herobine we know about was made on August 30, 2010.)

If the game started lagging while you were placing a block, sometimes, it would fail to update the data for this, meaning when you leave and come back.. It's gone-It was never saved to your file. ...Almost like Herobrine stole it.

Pyramids and temples are already features of the game-Herobrine has no part in this.

..Don't know where the "no eye" part came from, though.
