Earth Day- Earth From Space

Earth day is a day when nature/earth is appreciated. Everyday the earth is monitored by satellites and they see things the human eye cannot see. It's hard to get out of the earth because gravity pulls you down, and the only thing that can escape the earth is a spaceship/rocket ship. The sun spins around the earth all day, you know the sun and the moon have switched places when it starts to get darker in the sky. Half of the earth is filled with water/grass and also, if you were to jump off the moon, into the earth, you would fall fast due to gravity. What would happen if there was no gravity on earth? Would there be no life on earth? Will the earth ever come to an end? What would happen if the sun got TOO close to the earth of possibly the moon? We'll soon find out.
