That is where you are wrong. There is evidence of God in this world if one actually cares to look. My dad for instance when he was younger threw stones at a woman with his friends.

She immediately vanished and my dad and his friends heard her in the storage area outside the church...the door had a strong lock on it that required a key to open.

Later on in the night, my dad as he was walking, sensed something in the bushes to the left. He sensed that if he turned and looked he would not like it. He turned and saw a demon. Dad explained that it looked kinda like black tiles. He grew frightened and called upon God and the demon fled.
