Dear Alien

If you were to write a letter to an alien to tell them about Earth what would you want to say? Here is what I would tell them.

Dear Alien,

Let me tell you about Earth. Earth is the third planet from the Sun. As the Earth orbits around the Sun it turns on its axis, rotating around in 24 hours. It takes 365 days for one complete orbit. The Earth orbiting around the Sun causes us to have seasons. It is the only planet in the Solar System that has life as far as we know. Many people live on Earth. This is possible due to the Earth's atmosphere. Earth is home to humans, plants, and animals. Humans are lucky to be living on Earth. Earth is a wonderful place to be with lots of opportunities. There are many places to go and things to see. For example, there are many different states, stores, schools and zoos. You should come visit soon! 

                                                     Sincerely,

                                                        Miss K
