Why do some people deny the existence of God? (Only Atheists)

Hello and thank you so much for accepting my challenge. I wish you like, too. First of all, I should mention that I am Muslim. So I quote my Scripture and Diving Book which is Qur'an/Koran You said that God didn't answer our supplication. You're right somehow. But I must explain something to you: God wants us to pray. He loves listening to our supplication. Because when we pray, we show God that we need Him. We show our weakness. And God loves that. We are weak. But God is the Most Powerful. Everything belongs to Him. He is the Lord of the worlds. If we study on attributes of God, we'll find that He is not mean and stingy. When we ask God for something, He will grant us, indeed. As He said in Quran: "And your Lord says, "Call upon Me; I will respond to you." (Quran 40:60) So if God doesn't answer our prayer, we must know that it is our fault. We have done something bad which upsets God. We have committed sin. Another reason is the way we pray. We don't know how to supplicate. In the following, I tell you some ways which make God answer your prayer: 1. Remembering God all the time: There are some people who pray when they are ill, when they have problem, when they are in danger. It's not good at all and God dislikes it. These people only remembers God in hardship and forget Him when they are happy. We should always remember God. He said to Muhammad:"And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His countenance. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect. 18:28" And also, He says in another verse:" And when affliction touches man, he calls upon Us, whether lying on his side or sitting or standing; but when We remove from him his affliction, he continues in disobedience as if he had never called upon Us to remove an affliction that touched him. Thus is made pleasing to the transgressors that which they have been doing. 11:12" God revealed to David:" Remember me and pray in ease. So I will answer you in hardship." 2. We must pray sincerely, not heedlessly. 3. We must put our trust in God. We also must be sure that God will answer it. 4. We must be disappointed in anyone other than God. We must believe that no-one can help us but God. He is sufficient for us. 5. We must try and work after praying. For example, I am poor and ask God to grant me money. If I just sit at home and do nothing, do you think God answers my supplication? No he doesn't. Because I must work to earn money. So God helps me to get more money. Sometimes, we pray correctly, but God doesn't answer. because we have disobeyed him. Or we didn't worship him as we should do. For example, God says:" O you who have believed, enter into Islam completely [and perfectly] and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy. 2:208". God asks us not to follow Satan but we do. There are more reasons that God doesn't answer our prayer. For example, we pray for something which is bad for us. But we think it is good. God knows everything and wants the best for us. So he doesn't answer our prayer. "Perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not." (Quran 2:216) And also, God wants to answer our prayer, but he doesn't do so immediately. Because he wants us to keep praying. He loves us and loves listening to our voice. I don't know what you mean by stoning teenagers to the death. But I want to tell you something. Do not believe in whatever is written in the Bible. Because some parts of Bible (not all of it) is corrupted. The Scriptures are nonsense. If you have any question about Quran, I can answer you. But Bible is not the Word of God anymore. God dislikes when people disobey Him. Do you know why? God gives us everything. He always helps us when we need him. He always grants us what we ask Him. He is The Most Compassionate, The Most Merciful. "But if they turn away - then know that God is your protector. Excellent is the protector, and Excellent is the helper. 8:41" "Sufficient for us is God, and [He is] the best Disposer of affairs." 3:173 God grants us many favours. But He just wants us to do two things in return; worshipping him and thanking him for his favours. God doesn't need our worship. There are many angels who glorify God. Indeed, we need our worship. We offer prayers for our benefit. But we don't know it. We don't know the philosophy of worship. There are many people who forget God and enjoy their life. They do whatever they want. They do evil things and hurt others. They commit sin and corrupt themselves. Don't you think they deserve punishment? These peoples love this world and neglect the hereafter. "And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew. 29:46" God punishes the evil people. But it doesn't mean God hates them. No, God loves them. God loves all of us. He just punishes to purify the people. Sins corrupts us but the punishment of God purifies us. I want to tell you some verses of Quran: "[O Muhammad], inform My servants that it is I who am the Forgiving, the Merciful. And that it is My punishment which is the painful punishment. 15:49-50" "Say, "O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful." 39:53 "O my sons, go and find out about Joseph and his brother and despair not of relief from Allah. Indeed, no one despairs of relief from Allah except the disbelieving people." 12:87 " And when My servants ask you, [O Muhammad], concerning Me - indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided. 2:186" " And We have already created man and know what his soul whispers to him, and We are closer to him than [his] jugular vein. 50:16"
