The concept of order is simply a part of human understanding. When forces act upon oneanother in ways that we can predict, you can call that order if you like.
You can claim that things operating in a predictable manner is evidence of a designer if you like, but it isn't all that convincing.
For example, take the
snowflake. When they form, the water crystalizes in distinct, usually symmetrical* patterns which are defined by the conditions. The patterns are obviously not random, and once we learned how the processes involved interact, we gain an understanding of what is going on and can use that knowledge predictively.
*Most snowflakes end up with a flaw or two in their symmetry.
There are two ways to look at this really. One is to look at the snowflake as being a result of various forces interacting and producing a predictable phenomenon as a result.
The other would be to bring another factor into the equation and call it a designer, or a patron of order. For example, I could explain the apparent "design" of snowflakes by bringing magical snowflake gnomes into the mixture who meticulously craft every snowflake from solid ice which they conjure with their mystic powers.
Of course, the gnomes are not infallable, especially since they have a drinking habit which causes them to usually make a mistake or two during the snowflake forming process.

There, we now have two explanations for snowflakes. I am sure everyone is going to go put out an offering of booze for the snowflake gnomes in order to ensure easy shoveling this winter.
It is all a matter of perception which is very clear on the most basic level, but can be more difficult to grasp when things get more complex.
For example, if you take a big bowl full of mixed nuts of various sizes and gently shake it, the nuts will seem to order themselves. The larger nuts will have a tendency to rise to the top and the smaller nuts will tend to move to the bottom. There isn't a genie moving the nuts. They are just being acted upon by forces which operate in a predictable way. After a while, we learned how those forces operate, and thus were born the laws of physics.
Take a bucket of sand and pour it slowly onto a flat surface and it will form a conical shape. It is the same basic concept.
It is always forces acting upon oneanother. When we understand it and can predict it, we call it order and sometimes mistake it as being designed by something with intelligence.
You won't find many who will make that mistake with nuts seeming to sort themselves, but when you get to something that is not so easily understood, people start inventing patrons for the order they percieve.
It becomes genuinely easy to invent patrons of order for things we have virtually no understanding of, like the origin of matter. Still, I see no reason to start inventing entities to fill in the gaps in our knowledge, when we can just say "I don't know, let's find out." It may not be as emotionally satisfying, but it is intellectually honest.
