God exists. Just as you are existing, God exists. There is no reason why anyone should debunk the existence of God. The Holy Spirit is working in our presence everyday. Everything that we should know about God, He has reveal it to us. Why are we deliberately refusing to accept God? There would not have been anything like a world if there were no God. God is alive. I remember watching a film which the creators were trying to prove to some people who refuse to believe the existence of God that God exists. So, affirmatively God exists.
Wouldn't there be a Creator for such a massive and intelligently fabricated world like this? I think that it is wise for us to accept that God is in charge. Those who refuse to accept the existence of God might be doing so at their own detriment. The whole world was form and created by God. He is the architect who designs the world. There would not have been any good engineer to actual the structure than He himself. So, God is that intelligent Creator who made the entire world. Doubt no more; believe in God and you will see the salvation of God.
