God exists

First, the body was not made intelligently. We get cancer, we have an appendix with no function and yet it can get cancer and kill us, we are mortal, we are weak, we have the desire to go to war I could go on. Well, if a god created man, then I would give him a 0/10 because you claim that god is perfect and yet a perfect man cannot get a perfect score, which is why he deserves no points. Second, although you cannot prove in one sentences or even one book that a god does not exist. We can prove how unlikely it is that there is a god. The chances of a god existing are the same as the chances of the Easter Bunny or Santa Claus existing. There are so many things that contradict the existence of a god and even more contradictions of there being a personal god. Third, although it is not 100% certain, it is highly likely that the big bang theory created the universe by spontaneously creating itself from nothing, which quantum mechanics explains from scientific theory. Scientific theory unlike religion is tested and researched before we make any claims and religion could have easily made up evidence and made up their religion with NO EVIDENCE. Now for my many arguments for why I believe that there is no God: Why would god not want to reveal himself to us? By not revealing himself to us, he is allowing there to be doubt and different views on what god is. You might say that if god reveals himself then we will be forced to act perfectly because he is always watching. But if you believe for a fact that god is always watching, then why do you make mistakes? Also, if the universe had to have a cause, which you believe is god, then who created god? Why would you make an exception for your own case and not mine? Also, quantum mechanics verifies that the universe could have spontaneously created itself. It gives no explanation on how god could have been created. Also, if god is supernatural then there would need to be supernatural evidence of him existing. Jesus is not supernatural evidence because you have no proof that he existed. If you say that the Bible verifies it, then I say that what is your proof that the Bible is no made up but was actually written by God. Also, if god is supernatural and not bound by time then he would be spontaneously living in all time frames throughout history. If this is true, then god would have created everything at the same time throughout history. So, he would have created us knowing that we would fail him. If you say that free will is the reason that we betrayed him, then I would say that free will does not exist because our decisions are made by our brain. If we claim that god created us, then god created our decision making organ, the brain, in a way that would result in us betraying him. If you claim that the soul is what lets us do our decision making, then the same logic would apply from the brain. Also, why would a God create such a big universe and only care about earth? Also, why would a God have any desire to create us? It is not because of love because if god created us out of love then why would he allow us to fail him and cause all of our suffering in the world. Our actions are a result of what this god has created and if we betray him then god made us to betray him. For your argument, give me well-tested, concrete evidence that there is a god.
