Asphyxiation checks out
There is no cosmic frame of reference. Earth is moving, the sun is moving, the galaxy is moving, but you can choose any frame of reference within that. It'd be really silly to use the suns frame of reference, you'd use Earth's.
There is. Just because we can't correctly find and use it with our knowledge doesn't mean there isn't.
What would be silly is thinking that earth is some magical center of the universe.... We have abandoned this concept about 500 years ago.

The earth is not a magical center of the universe, it's just convenient right now to use it as a frame of reference no need to associate it to magical thinking.
I hear the universe is infinite, and no matter how far away from earth you go, there's just infinitely more universe. So like if you are standing on earth looking twelve billion light years that way and then twelve billion light years the other way you are in a sphere of unimaginable size right? But if you actually went twelve billion light years that way once you get there you can still look this way or that way and see twelve billion more light years every which way. So from that perspective, pretty much anywhere in the universe is the center of the universe...from a certain point of view...
The universe seems pretty infinite when viewed with our current tools and from our perspective. I would still argue that we can’t really be sure just yet. However, we can say it’s effectively infinite just like a lot of things in physics are effectively massless, effectively frictionless etc. You totally can make your calculations work really well even though your model cuts some corners here and there.
In many cases, you can even assume the Earth is flat and simple maths still works well enough. However, when you zoom out and start doing more complex calculations, you run into trouble and need to upgrade to a more sophisticated model. I would argue that the current assumption of the universe being infinite can fall into the same category.
