Earth, as you are aware of it.
[edit]to expand, some hold the solar system, some hold the galaxy, and some hold a bit beyond that as well, but the most common is the solar system.[/edit]
“Create” isn’t really explained in a detailed format that I’ve read yet (granted, I haven’t fully read through the book of Moses in LDS, so there may yet be a full creation detail that I’m not privy to, but as far as I’m aware, there isn’t a detailed list of how this was done.)
Hmm.
So God didn’t create the Universe or reality itself, but God did create the Earth or the Solar System or perhaps even our Galaxy…
That’s strange. How do you draw the line between what God created and what God didn’t create? How do we tell what in the Universe bears God’s mark and what doesn’t?
You don’t.
Or rather said, it doesn’t matter.
The LDS doesn’t concern much with where God ends, as it sees that God is, and is in control of everything that we can witness in this life as we are confined to be capable of.
Our comprehension by comparison to all of reality is actually extremely limited.
