Is God's Throne and the Earth a Footstool?

I have an issue with someone saying that what the heavens God's throne and the earth is footstool. And being like, isn't that comforting that we're God's footstool? We all find comfort in different places. These are the same people who would flip out over Islam because it means submission. Not all of it was thousands of years ago. They didn't know that pooping in the street was bad for your health. It turns out it's bad. You should do that.
