What you perceive to be good does not exist because every human is inherently selfish which is reason one. every persons brain is a neural network, and anything you choose to do is because of selfish reasons. The neurons in your brain interact to cause you to choose to do something therefore the only reason you are doing those things to because of a specific neural interacting coming from your brain which is selfish. also choosing to do something means you want to do it, if you didn't want to you wouldn't do it. therefore everything you decide to do is selfish. reason two, words are just defined by more words therefore any series of symbols called a word can represent any series of symbols. Therefore any word can be defined in any way and words only represent actions because something that doesn't describe movement describes nothing that moves. Therefore that is all sin is, a series of movements, we are machines; predictable cause and effect.
We don't think star ship enteprise exists because it was written about in a book. which god is god out of thousands, why does a god logically need to exist? explain that, convice me.
also, if god is allknowning and god created everything, god knew what would occur in the future. Nothing can be created it already had to exist because nothing is there to be created which disproves a god created everything.
