How a tornado went through a scrape yard creating a Boeing plane

One of the big arguments put in favour of existence of god is
"You see, how incredibly complex life-forms are. How much effort would it have taken to create us? Do you think we could be created without efforts of an invisible hand. If you don't believe in an invisible hand.You are  saying: A tornado went through a scrape yard and assembled a Boeing airplane."

The above argument appears gripping argument for existence of a divine being But it fails on its own premise to truly comprehend the efforts involved in development of complex beings like us.

We are a product of millions of years of recorded history. We started off as a pool of mixture of carbon, hydrogen, oxygen, sulphur etc. all atoms gamboling around when two atoms collided under appropriate conditions (say hydrogen and oxygen) and made water which was more stable compound. Atoms interact with one another (called reaction) for benefit of stability. Atoms reacted to form molecules. Molecules combined to form DNA's, RNA's etc. creating a first single celled life to come into existence in which every molecule served a purpose and existed. As time progressed we became more complex with more cells interacting with each other to create ever complicated life forms.We humans are ourselves a lot of organisms working in tandem. For example the bacteria in our stomach help us digest food.

In coming to the present form was not an instant creation of tornado, the so called tornado blowing through the scrape yard of hydrocarbons blew for a million years and more to make us what we are - a set of atoms co-ordinating with each other.

Hence, it stands to reason "A tornado can assemble a Boeing plane in a scrape yard, Just give it time." :)

My Interpretation of Karl Sagan's idea of "us".
