There are such things as unfalsifiable hypotheses. Fairly simple; it's something that cannot be proved as ludicrous. No scientific method or test could abate its validity. For example: I have a giant, invisible t-rex. It's a ghastly spectre, imperceptible. You don't believe me? Well, I have faith! Disprove it!... See what I'm getting at? You could claim that an anthropomorphic dolphin created the universe, and you could not be proven incorrect, as it's unfalsifiable. If you attempted to provide argument against this notion, (the theory of evolution, the big bang theory, etc.) they could simply invent a new retort - such as "He wanted it this way," or if you observed every inch of the universe and saw no god - they could say: "well, he's invisible," or, "lives in an alternative dimension."
However - the Christian definition of god is known to us. The Bible - the basis for its "belief". Dependent upon the version you succumb to, their idea is that the world was created by god 12,000 or so years ago. That man was forged from dirt, and woman from the rib of the man, and that the animals were created in a day. That god is responsible for the weather, personally responsible. All this, thought up 2,000 years ago by desert people. Primitive man. Before we were aware of the scientific mechanisms of nature. Of all these things, naturalistically explainable. The Christian's most prevalent retort is, "prove me wrong." I can. And I have. You, however, (an unspecific Christian individual) deny this truth in the place of your beliefs. It's like asking your mother or father how the soda machine knows what soda you want when you use it as a child, and they tell you there's a little man inside that drops it down. Before you're aware of the machinery inside.
The idea of the Christian god is this, in its sense. Prior used as an explanation. And now, it's used for psychological gratification, an escape from a fear of death, the rationalization of external subjective evils, a force to comfort in adversity, to gain an insurmountable bliss after life - so that their endeavors may not be in vain. The Christian god is ludicrous. Faith is not a viable opponent for objective realities. Denial does not abate the truth. Your truth is based upon your mindless and baseless interpretations, close-minded and deluded, denying all fact to further consolidate your religious agenda, your delusions. The Christian god is antiquated. It is absurd. It is time for humankind to evolve beyond its delusions, and transcend to a higher state of existence. Be free from the intrinsic egocentrism that enslaves us.
