There are a couple of things missing from his reasoning.
1. Yes, God is all-loving and all-knowing, but what about justice? Why should sin go unpunished or ignored? What about God's Holiness and purity? How can the fact we not holy not be addressed? How does God know? He set each of us up in the best possible circumstances so that we can best find Him.
24 “The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands. 25 And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else. 26 From one man he made all the nations, that they should inhabit the whole earth; and he marked out their appointed times in history and the boundaries of their lands. 27 God did this so that they would seek him and perhaps reach out for him and find him, though he is not far from any one of us. 28 ‘For in him we live and move and have our being.’ As some of your own poets have said, ‘We are his offspring.’ - Acts 17:24-28
2. God does indeed know us each better than we know ourselves. God knows all our rationalizations. Our opinions. Our Reasoning. That is why we stand condemned.
18 The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, 19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
21 For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. 22 Although they claimed to be wise, they became fools 23 and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
24 Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. 25 They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen. - Romans 1:18-25
3. What about repentance? This guy says he read the Bible. Did he understand it? He complains that if the Bible is right, he is going to hell because he does not believe, but Child molesters and rapist are going to heaven if they believe. He forgot, believing that there is a God is not enough.
19 You believe that there is one God. Good! Even the demons believe that—and shudder. - James 2:19
We've got to repent - turn from our sins. No one is going to heaven without repenting. If this guys ends up in hell it won't be because he was skeptical. It will be because he rebelled against God and ignored the salvation God offered him. We repent because we believe.
This is the Gospel in the Bible:
21 I have declared to both Jews and Greeks that they must turn to God in repentance and have faith in our Lord Jesus. Acts 20:21
4. Finally, this guy seems to think that he is good enough even thinks that God is pleased with him and the way he has lived his life. The Bible tells us different. All have sinned and deserve hell.
5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God. - Romans 8:5-8
God is not pleased with us. None of us. We deserve hell. God has provided a way out. A way we can have peace with God. We don't have to go to hell. Because of who God is, sin must be punished. It's not one-to-one or equal. Just like the punishment is more than what we can imagine, so it is the gift of heaven. We earned the punishment but God is giving you a gift.
I don't think he answered the question. As an atheist, standing before God, having lived your life without concern for God or his plan for you, what do you say when you look into Jesus' face? I don't think you are going to be able to say anything. I agree with this guy. At that time, there will be no excuses or anything anyone can say in defense. All that will be enough:
By myself I have sworn, my mouth has uttered in all integrity a word that will not be revoked: Before me every knee will bow; by me every tongue will swear. - Isaiah 45:23
God is in control. If I were this guy I would be concerned that God does know me better than anyone else. He knows why we deserve hell. He knows our sins and issues. Throwing yourself on God's mercy on Judgement Day is too late. Do it now. It's not just about trying to avoid hell or gain heaven - that's gravy. It's about getting to know who God is and to know him personally! It's about finding your purpose in Him. God's purpose is not for our comfort or just what is best for us. The point is for us to glorify Him. It's not vanity or ego. God deserves it. It is who God is. This guy does not know the God of the Bible but he can know Him. Reach out because He is not far from anyone of us.
