What do you mean by "Silent Planet?"

I don't call this the Silent Planet because it is peaceful or lacking in noise, quite the contrary. This world is silent because the rest of the universe hasn't heard from us since human kind was usurped from our rightful birthright.

In C.S. Lewis space series Earth was known as "the Silent Planet" because the rest of the universe was populated with aliens who had never fallen into sin like mankind. The angels who watched over these multitudes of worlds all had one question on their minds. What is the news from the Silent Planet? It speaks to the fallen nature of this world, on how we exist on a planet of fire and glass like Philip K. Dick wrote in his VALIS trilogy. A world that is haunted like John Keel proclaimed. A world that is silent and cut off from the rest of creation.

We bang our heads against the wall wondering how a loving God can create a world of pain and death, yet doesn't our own history tell us that this is a world forged by our own decisions? We were given free will and we only serve gods or the one God if we choose too. Isn't death, suffering and discovery all wrapped up in the shroud of our own potential?

What do you think? Is this the Silent Planet?
