OK but the earth is 4. 5 billion years old right? Hypothetically they wouldn't see anything when looking in our direction but we would see gz11 looking toward theirs?
Are you able to explain how the big bang happened not at a single point but everywhere at the same time?

1. Yes, they wouldn’t see the earth because our light hasn’t had time to reach them.
2. This does a pretty good job of explaining it:

Just ignore the extra dimension stuff.
