DNA proves the existence of a Master Coder.
The most basic living cell we know of requires the precise arrangement of something like 150 amino acids to exist. Those amino acids didn't all just happen to line up by pure chance and come to life on their own.
Someone wrote the code to precisely assemble those amino acids into an exact order that would produce that cell, then breathed life into it to create a living organism.
I build things.
I'm given a blueprint or drawings from someone and I build it.
At times I have to fabricate things completely on my own thought processes.
Granted, I have a starting point, but I also have a finishing point.
I start out, knowing what I want the piece to do at the end. From there, I gather my material and start cutting and fitting and building my piece. Sometimes I find out something in my piece doesn't work and I modify what I have, or I start over.
ALWAYS working with an end goal in mind or in design.
I am, for that piece, the intelligent designer.
Now let's take what you posted. Where I have an end product, I started off with already CREATED materials. Things DESIGNED so that I may use them.
The creator, like me, has an end design. Unlike me, he started with nothing. He "started" with an and design and then worked "backwards" designing EVERYTHING along the way, to build his creation.
I look at something like a DNA code and am amazed.
Somewhere 150 amino acids had to be designed and created and put into perfect arrangement, BEFORE the next 150 pieces of something were built from that and put into perfect arrangement, and so on, and so on, and so on, and so on, and so on, and so on, and so on, and so on, and so on...
As a mechanically minded person, I look at the human body and how it works and am amazed.
When I was younger, I was somewhat athletic. Between work and play, I've had a number of injuries. Those injuries have taught me more on the workings of the human body.
Add to that our synergy with nature around us. The DESIGN of individual animals, of individual plants, of individual insects.
EVERY living creature and organism took the same design energy to build it.
In the end, each of us, every living creature, fits into a finished end design.
