To me, rejecting God's existence is like rejecting my existence in this world. I mean the air we breathe, the trees around us, the people around us in flesh and blood. Not only we have five senses, but we have a logical mind that can formulate. Our body created so perfect that with just a little defect would bring us nearly to our deathbed! And where did all these things come from? Don't tell me it originated from Big Bang Theory or it came out from nothing. Things can't just pop out of nowhere. Scientifically, we've learned that every effect must have a cause. We're the effect of our parents' bond, our parents are the effect of our ancestors', and our ancestors were the effect of what? There must be a cause to our existence. It's so evidential and so obvious in front of our eyes, even tribal people who are uncultured, uneducated, do believe in some kind of god and do know how to give thanks. Some believe in mother earth, god of this, and god of that, and they offer offerings to them. We, educated people, who think highly of ourselves as smart and knowledgeable people, through many of our deep thoughts, cannot tell there's at least a God? Why is it so easy for uneducated, uncultured, and poverish people to believe in God, than those in modern society? One of the main reasons is because they now live in a world where people have everything. They don't need God to give them materialistic things; they got doctors, they don't need God to heal them. This is how people become conceited, thinking that they can build happiness with their own hands and brain. But u got to think, who gave you those hands and brain? Was it your parents? Your ancestors? If yes then, where did your ancestors got theirs from? If you think I'm unreasonable, then you are more unreasonable, because I say with proof of the world's existence, including you in it. Can you deny your existence?
