Your argument is if it hasn't been shown, then it doesn't exist. <<< Something used by those who lack the understanding of words and the actual universe created by writers.
Seeing as I already said "idk since i'm not kishimoto".. and clearly yall seem to have met kishi on this matter, thne i guess yall are right.
But people like me who don't want to claim something because its been said in the manga that its possible, but hasn't been demonstrated, are cool with simply "idk since i'm not kishimoto".
You want to claim yourself to be right.. go ahead.. just know you have 0 base for your argument. While your opposition has a manga base (but lacks a part to prove their argument) .
