If we are wrong about the creator if there is one... it's like being wrong about the host of where we are invited. It does matter.
Suppose you were walking down the street and noticed a party. Someone at the party invites you in. You assume that the person who invited you to be the host. You have a wonderful time, but towards the end, you find out someone else was the host. And it was someone you hadn't seen at the party. But you were told by another party-goer that this other person was the correct host. When pressed, you find out that the person who told you wasn't sure who the host is either.
How much does it matter that you were wrong about the host?
As far as I can see, very little.
