DE: Once, long ago...

[bjornwilde]

 For today's DE, I am going with a neat writing prompt I came across on Tumblr. Pick one or more!

Write a myth to explain:
...why the sun rises and sets.
...why leaves change color.
...why the sky is blue.
...why we are born and why we die.
...why the grass is green.
...where human beings come from.
...why birds fly and fish swim.
...thunder.
...lightning.
...why tsunamis happen.
...why it snows.
...why flowers lose their leaves.
...why snakes have no legs.
...where we go when we die.
...why volcanoes erupt.
...why the moon changes shape.
...how bees got their stings.
...why droughts happen.
...why people are different colors.
...the tides.
