The Bible gives two answers to this question

• 1. We know God exists by looking around us. We look up at the stars, the heavens and the intricacies of our universe (Psalm 8). We also look down into the complicated and complex nature of ourselves (Psalm 139). These point us to the existence of God.

But the Bible also realises that this first reason may be inadequate so it gives a more conclusive reason...

• 2. We know God exists because he came to earth in the man Jesus. Jesus claimed to be God. Jesus acted as if he was God. His followers recognised him as God and taught that he was God to their followers. If we had lived at the right time we could have seen Jesus/God with our own eyes, we could have touched him and personally listened to him.
