Moving the goalposts

Moving the goalposts is a logical fallacy that takes the following form.

1. 1st person, "Prove A to me!"
2. 2nd person, "This proves A."
3. 1st person, "That's not good enough, you've got to prove B as well!"
4. 2nd person, "This proves B."
5. 1st person, "That's not good enough, you've got to prove C as well!"
6. 2nd person, "This proves C."
7. 1st person, "That's not good enough, you've got to prove D E & F as well!"

And so it goes on, however much you prove if your opponent keeps moving the goalposts there's always more you haven't proved yet.
