Answer 1

Space, time and distance are all intertwined. Think of the age of the universe like the distance the crow flies from a to b. That’s 13.9 billion years.
Now think of the light from the furthest star that that’s traveling towards you, traveling over the bumpy hills of warped space time going up and down and round bends and curves before it reaches your eyes. That’s 45 billion years.
