Eli5 if time is relative and gets effected by gravity how could we possibly determine the age of our universe?

OP is under the assumption that because the universe is so big and so old that much of the available light that reaches us has been ‘tampered’ with by black holes along it’s journey.
The reality is that the universe is so much larger than you can possibly imagine. It is 99% empty space. It’s actually super rare that we see light that has been interacting with a black hole.
