Moon and earth! Moon !Earth ! Earth and moon ! Hit moon ! Hit earth ! Moon hits earth !

If the Moon were to collide with Earth, it would be a catastrophic event with devastating consequences. The impact would release an immense amount of energy, causing massive explosions, earthquakes, and tsunamis. The Earth's crust would be severely disrupted, leading to widespread destruction and loss of life. The dust and debris thrown into the atmosphere would block sunlight, resulting in a "nuclear winter" effect, causing extreme climate changes and making it difficult for life to survive. It's important to note that such an event is highly unlikely and not something we need to be concerned about in reality.
