Ludicrous arguments. Like prevailing theories in cosmology, interesting food for thought but most can never be proven, thus we relegate all such arguments to the realm of "theology" or "faith". Atheism is a faith, because no atheist has yet been able to prove his counter-theological argument, yet they expend no small amount of energy trying to browbeat people into believing there's is the only true faith. He accepts on faith that there is no God, just as others accept on faith that there is.
I don't have faith that there is no God. I cannot be 100% sure of what happens when we die.. As a matter of fact, I miss the comfort I got out of religion back when I was a believer. I just don't see any evidence that there is a God, so I don't live my life as if a God exists. (that's lack of faith)
When I became convinced that the universe was natural, that all the ghosts and gods were myths, there entered into my brain, into my soul, into every drop of my blood, the sense, the feeling, the joy of freedom. The walls of my prison crumbled and fell. The dungeon was flooded with light and all the bolts and bars and manacles turned to dust. I was no longer a servant, a serf, or a slave. There was for me no master in all the wide world, not even in infinite space.
I was free to think. Free to express my thoughts, free to live in my own ideal. Free to live for myself and those I loved. Free to use all my faculties, all my senses. Free to spread imagination’s wings, free to investigate, to guess, and dream and hope. Free to judge and determine for myself. Free to reject all ignorant and cruel creeds, all the inspired books that savages have produced, and the barbarous legends of the past. Free from sanctified mistakes and “holy” lies. Free from the fear of eternal pain, free from the winged monsters of the night. Free from devils, ghosts and gods. For the first time I was free.
There were no prohibited places in all of the realm of thought. No error, no space where fancy could not spread her painted wings. No chains for my limbs. No lashes for my back. No flames for my flesh. No Master’s frown or threat, no following in another’s steps. No need to bow or cringe or crawl, or utter lying words. I was free; I stood erect and fearlessly, joyously faced all worlds.
My heart was filled with gratitude, with thankfulness, and went out in love to all the heros, the thinkers who gave their lives for liberty of hand and brain, for the freedom of labor and thought to those who fell on the fierce fields of war. To those who died in dungeons, bound in chains, to those by fire consumed, to all the wise, the good, the brave of every land whose thoughts and deeds have given freedom to the sons of men. And then, I vowed to grasp the torch that they held, and hold it high, That light might conquer darkness still.
-Robert Green Ingersoll (1833-1899)
