Why would you present the idea that the ordered universe cannot have a designer?<quoted text>The fact is you cannot show nature has a designer.
Mechanism in biology is a different subject, your philosophical view only complicates any explanation. But they can be explained by causal evolution.
But crystallization is a example of a simple mechanism that has an ordered process than can happen, from simple laws of physics.
Planetary science shows us on larger scales how accretion and gravity build planets, no designer needed, but through a purely natural and mechanical process. Evolution shows us nature finds ways from a causal need and through causal mechanism it finds a way to refine a task.
Upon what basis do you make these claims?
