Umm there is no proof that Vivi was made. *spoilers* Quan fished him out of the mist. Vivi was made from the love in Quans heart mixed in with the mist. that is why Vivi remembers nothing before he met Quan (even though Quan wanted to eat him). so he might be human created by magic, or even from a diffrent planet (like Zidane). So lets end this dicussion and listen to "1000 Words" from FFX-2.
