Christians : Read this and explain the presence of god.?

The very presence of evil disproves the presence of god. If god is willing to prevent evil, but not able then he is not omnipotent. If he is able, but not willing then he is malevolent. If he is both able and willing, then there would be no presence of evil. If he is neither able nor willing, then why claim him god? If you consider evil to be the absence of god then you contradict yourself. The bible claims god is omnipresent so where there is evil there shall always be god. If god is everything and everywhere then with the absence of god comes the absence of evil. Then you might claim that evil is sin and sin came with freewill. Since god created everything he created freewill and since he is omniscient he knew that humankind would commit sin. Therefore god created sin and any so called all mighty being that creates evil with no justification is no god of mine. Heaven is also contradiction, in heaven you are promised freewill but there is no negative acts in heaven, which shows the absence of freewill and therefore defeats the purpose of heaven. The freewill excuse is also flawed in itself. God is believed to be omniscient, just as the bible states and he created free will, knowing that people would commit sin, freewill might have delivered the ability to sin, but god packaged it. Also freewill might have been created by god but he did not give this to us. He wanted us to be ignorant and except things as given. Humanity created its own freedom; your so-called god revokes it with rules and punishment. Adam and Eve had to take their freewill and god in return gave them eternal damnation. This again erts god is malevolent and as I said before, any god that is malevolent is no god of mine. Do you see how the bible is a contradiction? Just because a lot of people believe in something does not prove its true. A lie is a lie even if everyone believes it; a truth is a truth even is nobody believes it. At this point you probably aim to disprove my argument. The only way however would be to unreasonable. And as William Drummond said “He that will not reason is a bigot; he that cannot reason is a fool; he that dares not reason is a slave.” You really shouldn’t have anything to say to my statements. With that being said I will end with a quote from Bertrand Russell “I believe that when I die I shall rot, and nothing of my ego will survive. I am not young, and I love life, But I should scorn to shiver with terror at the thought of annihilation. Happiness is nonetheless true happiness because it must come to an end, nor do thought and love lose their value because they are not everlasting. Many a man has borne himself proudly on the scaffold: surely the same pride should teach us to think truly about man’s place in the world.” Think heavy on what I’ve said here.
