This short video illustrates how we would see the Moon if it had water and an atmosphere like the Planet Earth. The Moon has no water nor atmosphere (air), but it did have, it would look different when we saw it from our Planet Earth. Water would occupy the lower areas of the Moon and it's atmosphere might give the oceans the blue color the Earth has. Thus there would be oceans. lakes and continents and islands.
Use your imagination and give these oceans and continents of the Moon a name. Have fun, be creative.
