how do you know God is real?

No one can answer this question because no one can disprove or prove gods existence, but that being said there is no god. That feeling people claim to have with god is just in their minds, the brain is capable of more things than most people realize.

Remember we you were a child and you were certain that there was a monster under the bed and when you finally got the courage too look there was nothing there. God or should I say the idea of god is what people feel, not god himself, because he doesn't exist.

Edit: "The Man Who Saw God" stop pushing your book lol

Most of the ideas about God are made up, but God is a real phenomena and can be experienced face to face. This experience ends all doubt and belief on the matter. In fact, I wrote a book about this experiencing. Turns out we are all doing something that blocks this experience and failing to do something that makes it possible. If I can have this experience I believe anyone can.

We know that God is real because He has revealed Himself to us in three ways: in creation, in His Word, and in His Son, Jesus Christ.

The most basic proof of God’s existence is simply what He has made. “For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead; so that [unbelievers] are without excuse” (Romans 1:20). “The heavens declare the glory of God / And the firmament sheweth His handiwork” (Psalm 19:1).

If I found a wristwatch in the middle of a field, I would not assume that it just “appeared” out of nowhere or that it had always existed. Based on the watch’s design, I would assume it had a designer. But I see far greater design and precision in the world around us. Our measurement of time is not based on wristwatches, but on God’s handiwork—the regular rotation of the earth (and the radioactive properties of the cesium-133 atom). The universe displays great design, and this argues for a Great Designer.

If I found an encoded message, I would seek out a cryptographer to help break the code. My assumption would be that there is an intelligent sender of the message, someone who created the code. How complex is the DNA “code” that we carry in every cell of our bodies? Does not the complexity and purpose of DNA argue for an Intelligent Writer of the code?

Not only has God made an intricate and finely tuned physical world, He has also instilled a sense of eternity in the heart of every person (Ecclesiastes 3:11). Mankind has an innate perception that there is more to life than meets the eye, that there is an existence higher than this earthly routine. Our sense of eternity manifests itself in at least two ways: law-making and worship.

Every civilization throughout history has valued certain moral laws, which are surprisingly similar from culture to culture. For example, the ideal of love is universally esteemed, while the act of lying is universally condemned. This common morality—this global understanding of right and wrong—points to a Supreme Moral Being who gave us such scruples.

In the same way, people all over the world, regardless of culture, have always cultivated a system of worship. The object of worship may vary, but the sense of a “higher power” is an undeniable part of being human. Our propensity to worship accords with the fact that God created us “in His own image” (Genesis 1:27).

God has also revealed Himself to us through His Word, the Bible. Throughout scripture, the existence of God is treated as a self-evident fact (Genesis 1:1; Exodus 3:14). When Benjamin Franklin wrote his Autobiography, he did not waste time trying to prove his own existence. Likewise, God does not spend much time proving His existence in His book. The life-changing nature of the Bible, its integrity, and the miracles which accompanied its writing should be enough to warrant a closer look.

The third way in which God revealed Himself is through His Son, Jesus Christ (John 14:6-11). “In the beginning was the Word: the Word was with God, and the Word was God. . . . And the Word was made flesh, and dwelt among us” (John 1:1, 14). In Jesus Christ “dwelleth all the fullness of the Godhead bodily” (Colossians 2:9).

In Jesus’ amazing life, He kept the entire Old Testament law perfectly and fulfilled the prophecies concerning the Messiah (Matthew 5:17). He performed countless acts of compassion and public miracles to authenticate His message and bear witness to His deity (John 21:24-25). Then, three days after His crucifixion, He rose from the dead, a fact affirmed by hundreds of eyewitnesses (1 Corinthians 15:6). The historical record abounds with “proof” of who Jesus is. As the Apostle Paul said, “This thing was not done in a corner” (Acts 26:26).

We realize that there will always be skeptics who have their own ideas concerning God and will read the evidence accordingly. And there will be some whom no amount of proof will convince (Psalm 14:1). It all comes down to faith (Hebrews 11:6).

The more you learn of God and His will for you the more you will see that He is real in your life. If you don't talk with or listen to Him, it won't be any more of a reality than saying that you have friends...but you never talk with or listen to them.

People can't know if he is real or not, they just hope he is. Even if people (somehow) prove that there is no god, I'm sure that most people would reject that thought.

Continue to do what you are doing, he will reveal himself to you at just the right time. Speak to Christians around you, and have them tell you of their experiences. I believe now because I can feel that he exists and I see him in everything. I no longer require the opinion of others to tell me and I seek no worldly proof. My wish is that it will be the same for you because in the end, knowing that he exists is something that every individual will need to figure out for themselves, and my guess is God will begin to talk to you more and more each day

There are no gods.

They were invented to keep the peasants under control and to scam money from them.

Religion still works remarkably well among USians, doesn't it?

Seneca: Religion is regarded by the common people as true, by the wise as false, and by the rulers as useful.
