Detailed explanation-1: -Our Sun is 4, 500, 000, 000 years old. That’s a lot of zeroes. That’s four and a half billion.
Detailed explanation-2: -Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
Detailed explanation-3: -Similar studies show that the Sun is about 5 billion years old, consistent with the age of the Earth measured by radioactive studies. A third way to determine the age of the Universe involves measuring the ages of long-lived dying stars.
Detailed explanation-4: -Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
