How does Einstein’s theory of Universal gravitation explain the fact that the moon seems to be pulling on the Earth?

The moon is not pulling on the earth. The Earth is pulling on the moon. The gravitational force between two objects is a function of their masses and the distance between them. The Earth and the moon have very similar masses, so the gravitational force between them is similar. However, the moon is much closer to the Earth than the moon is to the sun. This means that the gravitational force between the moon and the Earth is much stronger than the gravitational force between the moon and the sun. This is why the moon is pulled toward the Earth.
