So, why is the sky blue? Well, i'm not completely sure. I was assigned to do this post without looking it up. My best educated guess is that, there are chemicals that create a blue color in the sky. By chemicals, i mean air. There is something around the earth called an o-zone. This o-zone was created a long time ago, by the first living species. The earth was originally like Mars, red and orange, because of the some chemical whose name I forgot.  These first species slowly made the o-zone, they were like cleaning the planet.

     My second guess which I think isn't even close to right is that lights are playing tricks on us. The grass is green because a green light reflects on the grass making it look green. I think lights are playing tricks with us! This could be po

They then asked themselves how this was possible. They then came to a theory that the continents were once a super continent. Eventually pangea started to break apart and become what is now.
