hehe......Well, I personally don’t believe in a such thing as "faulty humans". But, if you look up the definition of god in the catholic dictionary or whatever it is called, god is the "all knowing, and "all powerful" along with many other words. There are many problems with that definition. If something is "all powerful" it has the power to do all or to do anything. All-powerful means it can do anything. "all knowing" means it knows all. So, if something is "all powerful, and all knowing" it must know how each and everyone of us will live. Which would also mean that he would know all of our fates. Therefore, if he created a human, and that human ended up killing people and shit like that, it would be gods own fault for creating him like that. So for god to send him to hell or whatever, that would be his own fault.
A lot of other problems exist with that definition as well. Can god create a square circle? If you answer no, god is not "all powerful", if you answer yes, well, hehe, that’s just plain idiotic. If god knows all, then he would know are future...He would know the future to EVERYTHING...Including himself. If he is "all powerful" well then that means he can change the future or past. If he could do this then he would no longer be "all knowing". You see? You cant have both. It goes on and on. If he was all-powerful, then he can eliminate poverty, murder, rape, incest, etc. If he was "all powerful" and still didn’t change these horrible things, well then, god is a sick muthafucka who must get his kicks off of seeing a small percentage of humans live well, while the majority suffer.
Your ant farm example is irrelevant to this topic. You see, we are talking about "god" the "creator". If I had an ant farm, I wouldn’t have created the ants, only the environment.
I will now ask you the same question I ask all theist. Why do you believe in god? Are there any rational reasons why you do?
