1.) Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula .

2.) We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth .

3.) The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things .
