Question
Select the choice that best summarizes the timeline of early Earth.
If the Earth formed 4.6 billion years ago and radiometric dating of fossils and rocks date first life forms arriving at approximately 3.5 billion years ago, then 1.1 billion years of early Earth formation was without life forms.
If the Earth formed 4.6 billion years ago and radiometric dating of fossils and rocks date first life forms arriving at approximately 2 billion years ago, then 2.6 billion years of early Earth formation was without life forms.
If the Earth formed 3.9 billion years ago and radiometric dating of fossils and rocks date first life forms arriving at approximately 3.5 billion years ago, then 400 million years of early Earth formation was without life forms.
If the Earth formed 6.4 billion years ago and radiometric dating of fossils and rocks date first life forms arriving at approximately 4.6 billion years ago, then 1.8 billion years of early Earth formation was without life forms.

The best choice that summarizes the timeline of early Earth is:
**If the Earth formed 4.6 billion years ago and radiometric dating of fossils and rocks date first life forms arriving at approximately 3.5 billion years ago, then 1.1 billion years of early Earth formation was without life forms.**
This statement is accurate according to the widely accepted scientific understanding that Earth formed around 4.6 billion years ago and that the earliest evidence of life dates back to approximately 3.5 billion years ago. Therefore, there was about 1.1 billion years during which Earth existed without life forms.
