How old is the universe?

I’m reading a fascinating book of cosmology called “You Are Here” and written by Christopher Potter. It raises some challenging topics.
For instance, how old is the universe? Actually we have a reliable and precise answer to this question. It is 13.73 billion years, plus or minus 120 million years.

Katie Melua on the age of the universe: 12 or 13.7 billion light years? Very cool!

Time cannot be the parameter for the universe. we Indians believe that universe is (ananta), means it is startless as well as endless.

What evidence do you have for this belief that the universe is ananta?
