You find a watch on a deserted beach. You pick it up, and notice all the intricate parts. That's an interesting watch...
How is an animal such as a human being akin to a watch. A watch is precisely made, synchronized, and accurately put together.
This is an argument where either you accept it or dont. The form and functionality of the human being is evidence, or it is not.
Personally i see many flaws in the watch, so the watchmaker had to be unskilled in its makings. And i cant see mindless laws producing anything of any accurate significance.
The functionality just happens to be is a weak argument. Yet i see no god forthcoming.
A person can list a sequence of purely mindless incidental natural physical events that lead to the watch becoming, and thus, still, explain nothing of whether there was a watchmaker or not.
If you dont accept the watchmaker argument as proof, and a human being as evidence of some sort of a creative act, then obviously nothing will satisfy for evidence.
A materialist reductionist will always laugh at the argument due to the fact that there is no physical presence of a creator. They need only physical explanation, or there is nothing else existing.
The key point for me is why is there any utility whatsoever that aids the human in survival. And there is no mindless reason why it should be highly functional.
