You can look it up if you don’t believe me. Orthodox Judaism doesn’t have a supreme religious authority; it’s a general classification for ~hundreds of distinct sects and movements.
(Each movement has its own beis din, but there is not “high court” that unifies religious rulings across them. Which is why an eruv created by one group is often considered invalid by others.)
The whole joke is that the Jews will even take God to court (where God is the Judge, Jury, and Defendant), and win - I believe there's a whatever it is they have about this: God basically ends up saying "Ha, I like the cut of your jib".
(Talmudic interpretation doesn’t stress this story because it shows how much Jews love to argue, or because they can win arguments against God. It stresses the story because it demonstrates that the law has been received (“It is not in heaven”) and thus does not need to appeal to God. This, inter alia, is why nobody asks God for their opinion on eruvim.)
