What is the age of the Universe from the big-bang light perspective?

We all agree that the universe is around 14 billion years, from the perspective of a hypothetical observer moving in a galaxy, e.g. ourselves.

But what would be the age of the universe from the perspective of the first light that emerged from the big bang, given that it has been traveling at the absolute $c$ speed of light?

Lengths of time are not well-defined for objects moving at $c$ in Einstein's theories of relativity. That is to say, light cannot attribute age to anything.
