Anyone would agree that a motor or engine with it's multiple parts, each interconnected and working to fulfill a specific function did not come about on it's own. A car motor or washing machine did did not make itself either on purpose or accident.
So when you see the incredible complexity of purpose built, microscopic molecular motors inside the human body, at the very least, you know that it must points towards a designer.
One example of this is the Kinesin motor. This microscopic molecular motor carries proteins along a microtubule highway inside the human cell. It transports its precious cargo from the centre of the cell to the edge of the cell. Watch this short video and the presentation about bacterial flagellum in the next section an consider the astounding evidence this gives for the existence of a supernatural God who purpose built these amazing molecular motors.
Take a look at yourself. You are a work of art. This is yet another reason why a person should believe in God. Every day you get up and look in the mirror, you are looking at trillions of reasons as to why you should believe in God. Every one of your 100 trillion cells is proof of God as the divine creator.
I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. (Psalm 139:4)
ATP stands for Adenosine Tri Phosphate and is the energy currency of the cell. Adenosine Tri Phosphate, ATP, is produced by almost all living things in their cells by a tiny nano motor which is so small you could fit100,000 side by side inside one millimetre.
Almost every biochemical process in your body needs ATP. It is the energy necessary for life.
Many of these ATP molecular motors were needed BEFORE the first living cell could exist. This makes it impossible to believe in the theory of evolution. But it is yet another reason why a person should believe in God.
The bacterial flagellum has been called, "The most efficient machine in the universe".
We all have bacteria in our bodies which move around by using a whip like extension (flagellum) attached to a tiny motor inside the bacteria. The flagellum (whip) propels the bacteria along inside your body! You are looking at an animation of the world's tiniest motor. It's molecular (molecule) engine is powered by a flow of protons.
How big is the bacterial flagellum?
A bacterial flagellum is about 30-40 nanometers. What's a nanometer. Well first you have meters, then centimeters, then millimeters, then micrometers and then nanometers. OK, so how big is a nanometer? Pluck out one of the hairs on your head and look at the width. Depending on the thickness of your hair, it will be about 5,000 to 10,000 nanometers across. That means you could line up about 250 of these tiny engines from one side of your hair to the other! Note: we're not talking about the length of your hair which could be up to the length of a finger or hand or forearm. We're going across.
How many RPM's can your car engine do?
This little dynamo can do 20,000 to 100,000! Your car engine would probably blow at about 6,000. This engine can stop in 1/4 turn, and immediately rotate in the other direction at FULL SPEED (don't get any ideas about your car). This is an engineering marvel. It has intelligent design written all over it. It provides strong proof of God and reason to believe in God.
Scientists estimated that we have 500 to 1000 different types of bacteria living in us. And they are all there for a purpose. For example: some live in the stomach and help break down the food we eat so it can be digested. Bacterial cells are different and much smaller than the normal human cells. While there about 10 trillion human cells, there are about 100 trillion bacterial cells.
What's the point of this?
Well, just as no one would accept that the outboard motor for a boat made itself, neither is it acceptable to believe that the world's tiniest motor created itself. When you look at an outboard motor, you can see it has design written all over it. Likewise, the bacterial flagellum has design written all over it. And you cannot have a design without a designer. People design outboard motors. God designed bacterial flagellum.
What is Irreducible Complexity?
Simply put, the world's tiniest motor is made up of many complex parts which are all required to be functioning for the motor to work. If you reduced the number of parts by just ONE, this molecular motor would not work. The bacteria are an essential part of human life. Without them we would die. These bacteria could never have evolved over millions of years because we needed the complete package fully working, with all its parts right from the start. It had to be there complete when life began. And the complete package says someone made it.
Looking at this tiny motor we can only conclude that it could not have slowly evolved over millions of years because it needed to be there as the fully working motor in order to do its job in keeping us alive.
The world's tiniest motor, the bacterial flagellum, is another example of intelligent design - God being the intelligent life that designed it.
