The Ancient Builders were pigmen
As we see in Minecraft Story mode with Ruben, Minecraft pigs are very intelligent. The original Minecraft villagers were pigs, the structures in the Nether were clearly built by an advanced civilization, but the only intelligent species in the Nether (besides Endermen) are piglins. The Ancient Builder civilization in the Overworld was ended by the zombie plague, but this plague doesn't exist in the Nether. Therefore there was nothing to kill the Ancient Builders in the Nether, so the only logical explanation for what happened is they became the Piglins. So by this logic, the Villagers descend from the Pigmen (that would also explain their huge noses) and the Enderman descend from Pigmen who were colonizing the End
