I think the world will end by the moon if it crash in the earth. I would predict the world will end by the moon when it start’s getting to close to the earth. When the moon crash in to the earth I would predict that half of the earth will explode. If I predict this right I think the year when it could happen on the 3020. I think when the moon crash’s to the earth the moon will turn into more little Fragments and take out the rest of the earth.
