A plausible analogy for Macro Evolution.
Here is an example to show the value of the theory of evolution. There once was a lady who had just purchased all the ingredients for a cake. She was walking home when a pickup truck hit her at 50 miles an hour. The old lady did not die and is now living off the proceeds from her recent lawsuit in Palms Beach, Miami Florida. However, this story is about a cake.
The shopping bag she was carrying however was thrown into the air. The impact broke all of the soft paper bags that contained the ingredients and all the ingredients then fell into a bowl, which had fallen out of the pickup truck. There was a strong wind blowing which siphoned off the excess flour, sugar, powdered milk, it was very fortunate that the wind picked up most of the salt. The strong wind then settled down, leaving the bowl with just the right amount of what it takes to make a cake, but not before having mixed the contents up evenly.
It turns out that the strong wind was preceding a storm. The rain water, which was completely untainted by pollution or the like, began to fill the bowl. It stopped at just the right time so that there was not too much water in the bowl nor was there too little, it was just right.
After the storm had died down and eventually stopped, the sun came out and began to heat the bowl. Fortune shined again by way of the bowl having landed on the tarmac, which was now quite hot from the sun. This all amounted to heating and baking the cake.
By now, you might be wondering how the frosting got on the cake, but there is a very good reason it got there. You see, the bag of frosting had been thrown higher than the other ingredients and had become stuck on the stop light, the one that the old lady had failed to heed. The sun, which had heated the cake, also heated the frosting, the bag that contained the frosting then became too hot and split and began to cover the cake. Fortunately, for all, the wind picked up again and blew the frosting bag away before it put too much frosting on the cake.
That is how it is completely a hundred percent possible to have a cake made by nature. I hope this helps you to understand the marvelous theory of evolution. When I get the time, I think I might expand on this to show that if we change the cake to ginger bread and add some thunder, that it is possible to make the uncatchable little talking ginger bread man.
