God made the world in six days, but on the seventh day he/she noticed that he/she was shaping it in a bad way, so God regret what he/she have done.
And that's why and how Sunday become the regret day.
God really didn't liked the humans, so he/she planned a way to eliminate all humans. But, unlucky for God, Noah was listening when God was muttering on The plan, so Noah went home and made a gigantic boat, behind God's back, and let one male and one female of every species on earth walk onboard.
When God's plan was in charge, The flood, Noah's boat were floating easily and safely.
God was stunned.
"How did he... " God shook his/her head in disbelief. Now he/she had to figure out a plan to sink the boat. This could not be continued!
First he/she thought of letting it rain locusts, but he/she reminded himself/herself that he/she was going to do that to the egyptians.
Then a smile slowly appeared on his/her face. He/She will let cyclones rule the ocean, or in this case you could say the world.
And so he/she let his/her next plan enter the world...
...
Nothing happened! God just stood there and blinked.
"Myself daaaa... " God noticed something in his/her corner of the eye. It was his/her diary. The day was sunday.
Sunday...
(Now we jump over a few weeks, because you don't wanna know what God was doing under this time)
God's second plan of destroying the boat went on about the same way like the first one, and even the third and the forth.
Then God came up with a plan better than any other of the plans he/she had made up this far.
He/She raised his voice and uttered an incantation, and the water answeared him/her. The water began slowly to circulate around Noah's boat, slowly turning into a gigantic maelstrom. Noah's boat disappeared in to the maelstrom.
God sighed. At last the problem had vanished. He/She stopped the maelstrom.
God petrifies. Out of the water a boat arises the surface. And you could guess who. Noah.
God was furious. He/She let it rain a da... a very long time.
When God had calm down, God thought:
"Ok, I give the humans a second chance, because Noah and his wife are a very kind couple, and I don't think they will repeat their mistakes."
And then it stopped rain.
A short time after that, his/her son died on a cross, by the humans.
God didn't really liked the humans, that's why he ceated the appletree and the snake.
That's not true! God do like the humans, it's just that they shouldn't damage the grass they stand on. And the air, the fresh air. Humans can go away and do something else than breathe, because the air is too good just to be breathed.
