How old is the earth?


Question asked by: knowitall

Of course no one knows exactly how old the earth is, however science can give what it believes to be accurate estimates of the age of the earth using various dating techniques.

At present, the generally accepted estimate is that the Earth is between some 4.5 to 4.6 billion years old. This is based partly on radiometric dating techniques and partly on extrapolation back in time and looking at the universe around us.
