the age of the universe is dependent upon light that we've detected with our own instruments. it's an arbitrary human thing. besides time is subjective.

Well.. yes and no. Since light travels at a constant speed we can say that the universe is at least so old if not older. The passage of time is relative, not subjective as it is a dimension of space-time. The measurement of time, much like the measurement of distance is indeed arbitrary but still based on the empirical. A fun fact to ponder is that from the perspective of a photon travel is instantaneous. Relativity is fun =D.
