1) before the first true "landscapes"
2) after 99
3) after the continents started to drift
4) almost directly after the beginning
5) before the Grand Canyon began

Answer 1

Life appeared on Earth quite early in its history, probably after about 3.8-4.0 billion years ago.

Step-by-step explanation:

Life appeared on Earth quite early in its history, probably after about 3.8-4.0 billion years ago. The earliest evidence of life comes from indirect geochemical data and is from more than 3.83 billion years ago. Relatively unambiguous fossil evidence of life dates to 2.7 billion years ago. Therefore, option 4) almost directly after the beginning, is the correct answer.
