Proverbs 8:22 The LORD created me at the beginning of his work, the first of his acts of old. 23 Ages ago I was set up, at the first, before the beginning of the earth. 24 When there were no depths I was brought forth, when there were no springs abounding with water. 25 Before the mountains had been shaped, before the hills, I was brought forth; 26 before he had made the earth with its fields, or the first of the dust of the world. 27 When he established the heavens, I was there, when he drew a circle on the face of the deep, 28 when he made firm the skies above, when he established the fountains of the deep, 29 when he assigned to the sea its limit, so that the waters might not transgress his command, when he marked out the foundations of the earth, 30 then I was beside him, like a master workman; and I was daily his delight, rejoicing before him always, 31 rejoicing in his inhabited world and delighting in the sons of men. – Proverbs 8:22-31 RSV
Proverbs 3:19 The LORD by wisdom founded the earth; by understanding he established the heavens; 20 by his knowledge the deeps broke forth, and the clouds drop down the dew. 21 My son, keep sound wisdom and discretion; let them not escape from your sight, 22 and they will be life for your soul and adornment for your neck. 23 Then you will walk on your way securely and your foot will not stumble. 24 If you sit down, you will not be afraid; when you lie down, your sleep will be sweet. Proverbs 3:19-24 RSV 
The proverb indicates that the 1st thing that God created was wisdom. And then God created the world using wisdom as a primary tool. At its very basic root, this means that life makes sense. There are reasons for everything.
It’s also fair to say that the 1st thing that God-created with wisdom was likely to be systems. What is a system?
Definition of the system. Wikipedia. Peter Senge.
A system has inputs and outputs And the process. A process is a sequence of steps that leads from Input to output. This cycle repeats when called upon by a hierarchy, a plan that creates systems out of smaller systems.
Everything in creation is either a system or an element participating within a system.
