I was referring to "astronomers using another method estimated the age at 13 to 14 billion years." 14,000,000,000 minus 13,000,000,000 equals 1,000,000,000 years. If the actual age of earth was 13,000,000,000 years and they guessed 14,000,000,000 years, they were within 1,000,000,000 years worst case.

My cynicism for the wide range of years for the age of the earth is borne from the periodically-appearing news reports that yet another "scientist" or "group of scientists" has determined that the earth is really _______ (fill in the blank) years old.

The age of the earth is believed to be approximately 4.6 billion years.

My cynicism for the wide range of years for the age of the earth .....

We were discussing the age of the Universe. The methods used to determine the age of the Universe have nothing to do with the methods used to determine that age of the Earth.
