Age of the earth

Human are curious in their nature and they always wonder about the things around them so why would not they would not wonder about he earth. So they start to think about how old the earth is? Science has said lots of things about the age of the earth. They have given lots of theories about it and these theories are quite interesting for the people for the last hundred and sixty year.  Most of the geologist says that the earth is quite old about 4.5 billion years old which is a quite long time.

This time is way back the how the human itself are old. For counting the age of the rock the people usually conduct tests on the rock such as igneous rock not the sedimentary rock and by these rocks they calculate the test.  But the recent test on these igneous rocks were very astonishing as the age calculate was hundred or two hundred are old. So I would say as scientists are not confirmed about the starting of the earth how they can give us the data about the age of the earth. The ancient people think that the age of the earth was inconceivable and I also think that they are right.
