“How to live free without questioning the "why" of things? example: why we are here? why the laws of physics exists? why all and not nothing? why a giant round rock "decided" to have life in it?”

Your inquisitive nature is actually good. Why do you believe asking "why" is a problem and that it is something you should be free from? Seems you are interested, or at least have a small desire, in discerning the truth of things. Now, I cannot make too many guesses as to where you are just from your question, but my guess is the questions you gave as examples may be pressing on your conscience and that worries you. Not knowing the answers to them. I'm a Christian, and the Bible talks about how God gives us a nature of asking "why". He gave us a mind to think, to learn, to rationalize, to know right from wrong. Hebrews 5:14 says "But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil" and in Isaiah 18 "Come now, let us reason together, says the Lord". The Lord has a vested interest in reasoning and asking us questions about ourselves, the world, existence, and who He(God) is. Reasoning involves evaluating facts, making judgments, justifying choices with evidence, and attempting to persuade with solid arguments. The Christian worldview provides a robust foundation for reasoning, especially considering the immaterial, immutable, and transcendent nature of the laws of logic that underpin all forms of thinking. These laws are beyond human convention; they are discovered rather than invented. In a world without God, it would be difficult to say how these laws of logic came to be (which may be why your examples may be worrying you). However, the Christian perspective has the answer: the laws of logic “are simply a reflection of the thoughts and logical character of God, and as such, they reveal His logical, perfect nature” (Wallace, J. W., “Is God Real? Are the Laws of Logic Simply Human Conventions?” 1/16/19, https://coldcasechristianity.com/writings/is-god-real-are-the-laws-of-logic-simply-human-conventions, accessed 9/18/23; see 2 Timothy 2:13; Numbers 23:19; James 1:17; Romans 1:20). So if what I said peaks that asking of "why" then allow my a moment to share the gospel; The gospel of the grace of God is the glad announcement that God, out of sheer love and kindness, has provided the way for our salvation through Jesus Christ. By placing our faith in Jesus and His atoning sacrifice on the cross, we are granted redemption and complete forgiveness of our sins (Acts 13:38–39; Romans 3:22–24; 5:1–2, 16–17; Ephesians 2:4–5; 1 Peter 1:10). The God of all grace has covered our sin with the blood of Jesus (Romans 5:17; Hebrews 12:24; Ephesians 2:13; Titus 3:5; Revelation 1:5). He gives us His extraordinary, life-saving grace “not because we deserved it, but because that was his plan from before the beginning of time—to show us his grace through Christ Jesus” (2 Timothy 1:9, NLT). The gospel of the grace of God assures believers that their standing before God is forever secure because it rests on what Christ has done, not on their own achievements or failures: “When God our Savior revealed his kindness and love, he saved us, not because of the righteous things we had done, but because of his mercy. He washed away our sins, giving us a new birth and new life through the Holy Spirit. He generously poured out the Spirit upon us through Jesus Christ our Savior. Because of his grace he made us right in his sight and gave us confidence that we will inherit eternal life” (Titus 3:4–7, NLT; see also Romans 3:21–26). Our new identity and our eternal future are grounded in God’s kindness, mercy, and grace. The gospel of God’s grace transforms our lives (2 Corinthians 5:17), freeing us from guilt, shame, and the impossible burden of earning God’s acceptance (Romans 5:1–2; 8:1–2; 2 Corinthians 12:9; Titus 2:11–14; Hebrews 4:16). It allows us to receive God’s love deep in our hearts (Romans 5:5; Ephesians 3:17–19), to live in gratitude (Ephesians 5:20; 1 Thessalonians 1:2; 5:16–18), and to extend grace to others (2 Corinthians 9:8; Colossians 3:12–13).
