Question 

In the beginning God created the heaven and the earth, and the earth was without form and void and darkness was upon the face of the deep and the spirit of God moved upon the face of the waters. What does it mean, “God said, Let there be light?”

Answer

Okay, let me see if I can answer that. Now when God created, He created everything in six days and one of the things He created was light. Now I don’t know how to tell you all of the scientific things but you know what light is, right? Because you know when it’s on and you know when it’s off. So God created light all by itself and it wasn’t until later that He created the sun and the planets and all of the other things that hold the light. So first God created light all by itself and then later He created all of the planets and stuck the light on them, so when you look up into the sky you see the light attached to the planets and the sun and the moon and the stars and all of that.
