How can you tell how old a galaxy is?
We measure the age of the galaxy by finding its distance from us. Gravitational lensing makes the galaxy brighter, so it can be observed at these immense distances, it isn’t directly used for finding the distance, but without gravitational lensing, the galaxy wouldn’t be visible.
