(b). Scientists believe the Earth began its life about 4.6 billion years ago. The Earth formed as cosmic dust lumped together to form larger and larger particles until 150 million years had passed. At about 4.4 billion years, the young Earth had a mass similar to the mass it has today.
Report Abuse. I would think that the moon is about as old as the earth, and would guess that to be about 4.5 billion years. However it is really difficult to document, as none of us where on earth at that time. They use carbon dating to document how much carbon is released from a rock after it is formed. So the 4.5 billion year estimate comes with a disclaimer. It might be off by 4.4 billion years younger, or many trillions of years older than we think it is.
