I didn't name it. It's in ancient Sumerian texts.
i named a planet "shoppingisexpensive"
I just don't see any reason why they would make up stories.
and why would i make it up?
my planet exists just as much as nibiru exists.
the only difference is that nibiru was made up a long time ago and i just named my planet a day ago.
just wait 3000 year and my planet is exactly as true as nibiru is.
