People trie to find out so often what those who wrote the holly bible once could have seen and what happened realy.
Here is the answer. They have seen a guy creating the world with Photoshop.
First he created a world with a dark landscape, then, with a magic stick he said, there should be light, and right away the sun appeard and a flare was there as well. Then he said, it's so empty here, there should be life and animals appeared in the landsacape. So, came the saturday and he took rest. Just by mistake, the magic stick felt down and did some by its own and a horrible creature called human appeared with his technology to shoot at this world he created.
So, people, now you know what happened once and people trie to find out so hard. :)
