Ireneus: Look at the Periodic Table which is the perfect symbol of order, and it is typical of the universe.
Hmmm, not sure what you mean by that statement.
I'm guessing you mean the Periodic Table of the Elements (PTE). I'm wondering how familiar you are with it, its history and usefulness.
In what way is the PTE a "symbol"? And how is it "perfect"? In what sense do you mean?
Hopefully you understand that the PTE is a human invention attempting to help us to understand physical reality such as it is. It is a model that many scientists have contributed to in order to makes sense of things. As a tool, it is particularly useful, not just for its explanatory efficacy but also for its predictive power. But again, it is a human invention, not a product of nature. It was not discovered wrought whole, but was put together piece-by-piece and bit-by-bit over several centuries.
There is no question that we humans have come to understand much of nature's secrets and mysteries. And yet much remains ... no doubt more than we can imagine.
Even with all that we know, there are things that yet defy explanation as to why. For example, despite the clear overall patterns that underlie the organization of the PTE, there are many things that are exceptions. Why? Who knows. They just are. For a relatively easy example, can you explain why both chromium (Cr) and copper (Cu) have only one valence electron when all others in the d-block of the 4th period have two?
I would say THAT is "typical of the universe" -- just when we think we see a discernible pattern, there's an exception. Better get used to it.
Let's take up another example from math and music: the Pythagorean Comma. It is rumored that this was a thorn in Pythagoras' side because it didn't fit his simplistic worldview. Did you know that it was one of the secrets of his little cult and that to reveal it could result in the death of the betrayer of said secrets? Legend has it that Pythagoras personally drowned Hippasus because he developed a proof that showed that the square root of two was an irrational, never-ending number. Pythagoras had taught that all numbers could be expressed as ratios of integers, and Hippasus had proven his divine teacher wrong.
Cult leaders don't like to be proved wrong.
We humans strive to understand things. But often we try to make the world and the universe fit OUR views, beliefs and understandings rather than simply letting things be as they are and then adjusting our knowledge and understanding accordingly.
Most humans do not do well with ambiguity or cognitive dissonance.
Learn to embrace it ... or continue seeking meaning in the myths and legends of the Bible or the pareidolian manifestations of "god" such as "the face of the Virgin Mary on a toasted cheese sandwich." — New Scientist, 24 December, 2011

Hail Mary, full of cheese,
the Lord is with toast.
Blessed art thou amongst sous-chefs,
and blessed is the fruit of thy grill, Cheese-us.
Holy Mary, Mother of Toast,
pray for us grillers,
now and at the end of our fast. Amen.
