<reasoning>

Analyze gravitational relationships

The Earth-Moon-Sun System is held together by Gravitational Attraction. The Sun's massive gravity keeps both Earth and the Moon in orbit around it.

Determine orbital changes

Without the Sun, the gravitational pull holding Earth and the Moon in their solar orbit vanishes. Consequently, their Orbital Relationships change, and they would fly off into space.

Examine Earth-Moon binding

Because the local gravitational pull between Earth and the Moon is much stronger than the Sun's pull on the Moon relative to Earth, they would remain gravitationally bound to each other.

Describe the final motion

The Earth-Moon system would travel together in a straight line through interstellar space, while the Moon continues to orbit the Earth.

<answer>
If the Sun did not exist, the Earth and the Moon would fly off together into deep space in a straight line, with the Moon continuing to orbit the Earth.
