Someone In Golden Armor

Hello, I don't know if this was mob or a player. I'm Gonna Tell You The Story (may be short).
So I was In Menu, I clicked Single-player and made a world called New World, I didn't change name. So it was loading. I started world and started my first survival. I didn't even know how to craft a pickaxe or a sword yet because i was a bit new. I tried surviving but it became dark and I had less food in hunger bar, it was probably because I forgot to kill some animals, or I ate food too early or I didn't even find an animal to kill, zombies and creepers were running to me, I was escaping, I had only 2 or 1 heart left. When I came to water and I saw someone in golden armor not looking at me and showing me his back. He seemed like he is ignoring me, he was holding sword like an player. I was confused if it was a skeleton because skeletons can have swords and armor too. I encountered some skeletons with armor and sometimes a sword and armor in their hand. there were some squids on water. I was scared they would kill me so I placed some woods to get to the guy. When I came closer to him he turned to me like a player and killed me with diamond sword or other. I wasn't even afraid but confused. I re-spawned and I tried finding him and I couldn't find him again.
(Sorry if there are no screenshots of him because i didn't have anything to screenshot with, but this never happened. Don't believe it. and before i end writing i didn't encounter him at all)
