The earth has life in it thats why we could live in it, animals or plants also.

If the earth does not have life I don't think there is anything that can survive in it.

The earth was created by God to suit man and everything we need to survive and thrive is in it.

The oxygen, hydrogen and all other natural gases and natural resources comes from the earth and they have life in themselves.

The fact that living things are on earth is a proof that the earth has life.
