Also finding a piece of solid metal at the bottom of a pit isn’t exactly comparable to growing a new head.
But finding something that was flow into the gas giant and disintegrated is.
Why do you keep insisting that it fell into the gas giant?
Because it did.
Just because Luke got sucked into a tube that eventually dumped him onto an antenna (a very bizarre thing that only happened for plot reasons I might add)
No, you may not add that false claim. The thing was clearly waste disposal system and not some “bizarre thing”. Though, it also serve a plot nicely.
