The entire creations is the primary prove of the existence of God. If you are wondering whether they is a God, look around you and observe the animals running around you. Can you see the numerous insects and wombs that are crawling around us? How do you think they came into existence? See how especially made and form each creature is. Do you not think that these could only be the creation of an intelligent Creator. That creator is God. God made everything that we are seeing. He formed the various breeds of the animals and other creations. This is the primary prove that there is God.
Another proof of God's existence is you yourself. I am the proof of God's existence. The intelligence I possess came from God. The beautiful appearance that I am made up of is from God. I am the very very work of God. So, if you are still in doubt about God's existence, consider yourself then you will be convinced that there is God. You are the proof of God's existence. He made you.
Some thinking people claim that God does not exist. They say that the things that we are having in existence came from an uncertain explosion. How possible could an explosion produce such an orderly and organized world. That is not the truth. The truth remains that there is a God who created the entire universe.
