Moon and another attributes of the real Earth. Why?

[CodingSquirrel]

Please, stop. Im not talking about some "minor" things like water, air, trees, animals. These things really can be o the other planets, also having another shape.

But Im talking about the much more fundamental things, that make us think, that the game world- is the clone of the Earth. The Moon (one, visible only at night, have the same size), for example.

Another planet with the same colored seas, same air composition, same types of trees, many of the same/similar animals, and humans just like us. All of that stuff that surrounds us every moment of play and is astoundingly similar to real life, that's minor. But only one circle in the sky, that's major. That's gamebreaking and totally ruins my immersion.
