If someone was completely ignorant of modern science and had never been exposed to the discoveries of the last thousand years or so and they were to sit down and read the six day creation story in Genesis they would come away with a view of the universe in which stars were just ornamental little lights to make the sky a little prettier and the sun and the moon would just serve the purpose of providing plenty of light in the daytime and just a little light at night so it would be easier to go to sleep. The earth would be at the center of everything and what we recognize as the universe wouldn’t even exist. In reality the universe is so massive that we really don’t know how big it is but we know that it’s at least 14 billion years old because that’s how long it took the light from the furthest stars we can detect to reach the earth. The earth itself is just a tiny speck in space and is not the center of anything.
