Every right thinking person must believe in you God. In fact, every person who uses his mind rationally will believe in God. That is why the Bible says that it is the fool who says in his heart that there is no God.
The Bible calls such people who reject the reality of God's existence as fools. They are fools because everything that exists tells us that there is a God. How could a person whose brain is working perfectly well ignore all these beautifully designed and created worlds and conclude that there is no God? Who designed the world? Who out it in place? How would you sit down and conclude that these all just happened by chance? Are you a creature of chance?
The computer that we are using is able to serve us because man created it and made it so that it could perform a certain function. There are many technological devices but each of them performs a specific function. So, how do we have such well designed and unique creatures without a Creator? How could man be different from a lizard in its structure and mentality if someone did not make them that way? Friends, it is useless and foolish to debunk the existence of God.
