The sun and moon emit different energies. It would be silly to think the moons light is a reflection from the sun. Not to mention stars have been seen through the moon.

Scientific Theory

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.[1][2][3][4] Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge.[5]

The strength of a scientific theory is related to the diversity of phenomena it can explain, and to its elegance and simplicity (see Occam's razor). As additional scientific evidence is gathered, a scientific theory may be rejected or modified if it does not fit the new empirical findings; in such circumstances, a more accurate theory is then desired. In certain cases, the less-accurate unmodified scientific theory can still be treated as a theory if it is useful (due to its sheer simplicity) as an approximation under specific conditions (e.g., Newton's laws of motion as an approximation to special relativity at velocities which are small relative to the speed of light).
