What do you think of "the 5th Way" of Aquinas? Summary and explanation of the argument (from Wikipedia):
Summary
We see various objects that lack intelligence in the world behaving in regular ways. This cannot be due to chance since then they would not behave with predictable results. So their behavior must be set. But it cannot be set by themselves since they are non-intelligent and have no notion of how to set behavior. Therefore, their behavior must be set by something else, and by implication something that must be intelligent. This everyone understands to be God.
Explanation
This is also known as the Teleological Argument. However, it is not a "Cosmic Watchmaker" argument from design (see below). Instead, as the 1920 Dominican translation puts it, The fifth way is taken from the governance of the world.
The Fifth Way uses Aristotle's final cause. Aristotle argued that a complete explanation of an object will involve knowledge of how it came to be (efficient cause), what material it consists of (material cause), how that material is structured (formal cause), and the specific behaviors associated with the type of thing it is (final cause). The concept of final causes involves the concept of dispositions or "ends": a specific goal or aim towards which something strives. For example, acorns regularly develop into oak trees but never into sea lions. The oak tree is the "end" towards which the acorn "points," its disposition, even if it fails to achieve maturity. The aims and goals of intelligent beings is easily explained by the fact that they consciously set those goals for themselves. The implication is that if something has a goal or end towards which it strives, it is either because it is intelligent or because something intelligent is guiding it.

One way to explain this is to start with the scenario of humans creating new things. Humans can create things that will not and do not appear naturally by natural laws; build a long suspension bridge made of alloyed steel. This bridge will not just appear by natural selection or by just natural physical forces. It can only start within the human imagination. It has an ethereal beginning, with the designer making it first on paper; or computer screen, before anything material or tangible starts to move. The designer will also have creative liberty, so the bridge does not have to stay within a strict design pattern. The selection process itself has wiggle room. Although, the design chosen will need to accommodate, the needs of physical reality; weather, wind, load weight, cost, etc.
Once the designed is approved, we then start site preparation and construction; moving matter, none of which is left to chance. The best planners make big bucks. This is all planned out in advance. We do not build the bridge, on a whim, in trial and error stages. Instead, we work from a preconceived master plan. A acorn becomes an oak tree. This is not left to chance. It follows a sequence of changing steps and needs, even with nature and weather not being homogeneous. This is in already built into the acorn design.
This human creation analysis, is why people often postulate God or a Cosmic Watchmaker, who plans things before they appear. Humans are a prime example of this process actually being possible, and more advanced than just chance. We do not build a bridge by gathering materials and throwing dice. It takes a lot of planning, in advance, to make it come out right.
I can explain deeper, with a simple spin on two basic science principles. We live in space-time, with space-time made firm by matter/mass. The mass of the sun, creates an expanding space-time zone, radially outward, based on its mass. This profile of space-time follows the sun's mass as the sun moves in the galaxy.
I postulate there is also independent space and independent time, where space and time are not tether bu mass, like we have with space-time. This other realm go independent space and time, is not based on matter or mass. It can only become matter, if space and time become tethered.
The bridge. above, being designed on paper, is not yet made of material, matter or mass. It exists more where space and time are not connected; imagination, which makes these ideas more ethereal, and not firmly fixed into material reality. In the imagination, we can make the bridge out of spaghetti, but that design cannot be tethered into space-time. But it is still humanly possible to imagine this. But since it cannot be tethered into space-time, it will fail in space-time or reality.
Separated space and time, has more options than just space-time. We can imagine fact and fiction. Space-time is a subset of separated space and separated time, since space-time cannot naturally build imaginary castles or alloy bridges. However, human can build these castles. The clock maker is not part of space-time, but he would be part of the larger set, called separated space and time, where planning can be done in infinite ways. However, with space-time a subset, only some of this endless ways, will not only work in separated space and time, but also within space-time; imagine and build a real castle.
The black box approach; statistical, appears to sense this fictional and fact nature of separated space and time, with not all fiction selected; mutation that does not add up to progressive reality. Not because its is bad, but because it cannot merge with space-time, but it remains ethereal. It can still be thought about, but natural laws of space-time cannot use it, directly. Learn from mistakes.
I also combine this to the second law of entropy, which states the entropy of the universe has to increase. Entropy is connected to complexity with separated space and time being a more complex state, since it has so many extra fictional options beyond space-time It appears, separated space and time, being of extreme entropy, is the drive behind the 2nd law in space-time. Since entropy has to increase in space-time, change is inevitable; clock maker. Since entropy has to increase within space-time, space-time itself, begins to look more like separated space and time; live and consciousness appears.; human creation advancing space-time.
