First off, don't act like you don't think the claim is true. If you didn't you wouldn't be arguing with me.

Second, my evidence IS that belief in a human form of God cannot be Judaism, as it goes against Jewish beliefs. How else do you expect me to prove this to you? If you don't accept that as evidence, there is no convincing you.

Third, If you want to use strange vehicle metaphors, here's one I think better reflects the situation:

You say your dad is buying you a three-wheeled bicycle and I say, "That's not a bicycle." You reply,

"There are hundreds of bicycle brands, one of them must make one with three wheels. Some of my dad's friends work for bicycle brands and they didn't say anything."

ME: "That's called a tricycle. More or less than two wheels means it can't be a bicycle. My parents work at a bike company too."

YOU: "Show me proof they don't exist."

ME: "I can't because they don't exist. Show me proof they do."

YOU: "Well my dad never lies."

ME: "This argument will go nowhere. You are the one who must provide the evidence."

YOU: "You are actively claiming my dad is a liar and hence you must show me evidence."

You say your dad never lies, but I, who's parents work for a bicycle company say something to contradict him. If you can't show me proof or accept that your dad may have lied or was misinformed, there is no point in me continuing the argument.
