The age of the earth or the age of the universe? Scientists think the universe is 14.5 billion years old. How they can measure that is a mystery, since the “year” is how long it takes the earth to go around the sun, and there was no sun and no earth at the beginning of the universe.
At this point, all the reporters have left the room, looking for someone else to trap.

You are mistaken in a number of ways. First, there are a number of different ways of defining a year besides defining a year as “how long it takes the earth to go around the sun,” which is of course changing slightly all of the time and year to year. See for example the definitions for a sidereal year and other types of year measurements.
Secondly, Time and the Universe did not and are not going to cease to exist because there was no Earth around by which its orbit about a star could be used by humans to reckon divisions of time.
Thirdly, how we can measure time and reckon the age of the Universe is no great mystery once we developed the instrumentation needed to observe the Universe backwards in time to its earliest beginnings.Due to the properties of light and matter the observations of the Universe are literally a window backwards in time to the birth of the Universe.
