What could it be else except for a spirit? I mean, Momoshiki's body was destroyed completely without a single shard staying intact, while the image of his before Boruto retained only a minor signs of damage like broken horns. The special characteristics necessary to see this image (Boruto's Hyuga blood and Sasuke's Rinnegan) also imply it was a chakra ghost. The same way, Naruto/Sasuke were able to meet Hagoromo's chakra ghost as the reincarnations of his sons.

As I already said, I added this part in an artcile, since I think that way. Because other users didn't remove anything from it, I assume I'm correct more or less.
