You have acknowledged that absolute truth exists, and that you know some things to be true. The next step towards the proof that God exists is to determine whether you believe that logic exists. Logical proof would be irrelevant to someone who denies that logic exists. An example of a law of logic is the law of non-contradiction. This law states, for instance, that it cannot both be true that my car is in the parking lot and that it is not in the parking lot at the same time, and in the same way.
