Theories and calculus? What does calculus have to do with the age of the universe?
Check out this picture of the Andromeda galaxy. It is 2.5 million light years away. That means that the light we see today came from the Andromeda galaxy 2.5 million years ago. Then check out these galaxies which are about 13 billion years old. These aren't theories or "calculus," but actual pictures of things in the sky that are older than 10,000 years.
Glad I could oblige.
If you tell me that picture of Jesus riding a brontosaurus is a fake, I’m really going to be mad.
Are you saying a God that created everything could not make light in flight?
