Now I definitely think that only a fool can reject the logic that proves that there is a creator of all things. We don't need to see a painter to know that the painting had a painter. We don't need anymore proof than we already have which is in the logic.

Don't allow these so called "intellectuals" to cause you to fail to give them God's Law. Take them through the Law and if they are at all reasonable, they will admit that their conscience is convicting them and they will admit that they know they are guilty. If they don't, then do not waste your time. There are many people who will never change and they will spend eternity in Hell. For wide is the gate and broad is the road that leads to destruction, and many enter through it (Matthew 7:13).
