The universe is estimated to be approximately 13.8 billion years old.
Scientists have reached this conclusion using two main methods:

Cosmic Microwave Background (CMB): By studying the oldest light in the universe—the afterglow of the Big Bang—missions like NASA's WMAP and ESA's Planck have calculated this age with high precision (around 13.77 to 13.8 billion years).

Expansion Rate (Hubble Constant): By measuring how fast galaxies are moving away from us, astronomers can "rewind" the expansion of the universe to find the starting point.

While 13.8 billion years is the widely accepted consensus, some modern studies occasionally suggest slight variations as we refine our understanding of dark energy and cosmic expansion.

From the perspective of the photons of light that gave us that data time doesnt exist.

Let me ping someone who is passionate about this topic.

There are new models that challenge the 13.8 billion year claim and instead double the age to 26.7 billion years. These sciences are not definite and unquestionable.

The discovery of many fully formed galaxies farther away than expected puts all these theory models under futher scrutiny. All of these models have issues and holes that show how they are not fully acceptable.
