Alternatively, all of nature can be explained by mathematics, rather then being based on it.

Three tress just sitting there in someone's yard

HOLY SHIT, Look at that, there's exactly three trees, its like it's reality is based on math or something :O

Incorrect, of course the universal language we use to describe nature is everywhere in nature.

Well of course does the universal language we developed describe things universally

This reminds me of a comment, I read a long time ago.

It was something like this: "I played The Sims, and everything was business as usual, my Sims went to University, and got a degree in Computer Science until they proved they live in a simulation. I stopped playing Sims for that night."

Someone building the simulation was like “yeah, let’s simulate diarrhea and make people have it just for funsies”.

Well, if we are in a simulation, there is very likely an admin ;)

But... We invented mathematics in order to understand nature

Our "universe" simultaneously is and is not a simulation because reality is relative to the seer. It's a fun thing to think about but pointless due to our limited understanding on what would make one universe 'real' and another a 'simulation', since really they're one and the same, just at different scales. It is interesting to think about though whether or not our universe has a parent universe which it exists inside of. And if so how deep that nesting goes. If our universe isn't contwined inside something else, does that mean our universe simply is everything? No way to really know.
