Does Fiel Exist?

I can not not see any proof that he does or does not.
I've also seen many names for Fiel.
Paul, Fiel, The Forbidden One...
Is Fiel a Trinity?
Personally I think if you loook deep enough Fiel is in all of us.
Exploding Chinchillas out of our chests.

I am quite sure Fiel is not and has never been inside me.
