(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.
the Earth is about 4,500 million years old. there is evidence that living things existed on Earth at least 3,500 million years ago. no one was there to record how life began. early Earth was hotter and the atmosphere consisted mostly of carbon dioxide (with other gases such as ammonia and methane)
