For me, many people believe in this man called God. He is all powerful and created the heavens and the earth and made all the people and said, "Hey, go and look after the world and take care of the animals. I'll be in heaven, so if you do something bad, you can talk to me "." It's great, "said a man and a woman. So they did something naughty with an apple and a snake, but then everything was fine. Then there was a flood, and water well anywhere. "Save the animals!" "Is that all?" "Not only are two of each", "just sounds good". So Noah running around getting all the animals and put them on the boat.
Then God sent his son Jesus to earth, but because there was no Jeremy Kyle everyone thought his real parents were Mary and Joseph. Mary said all she was a virgin, and so it was written in the book. Then Jesus ran to do loads of magic and stuff, and then people did not like that so they crucified him. Then he returned, he said everyone was fine, and went to heaven.
The fact that it was a hundred years ago. It happened. That's it. You can not say that God is a young, because he was always there. If you believe or not (I do not). Bible is ancient. Those who wrote it is not even around anymore. Thus, God is old, if you will.
