    All known events in the universe come from nature.

    Yes. Everything is governed by natural law.

    Yes it is. But I'm not entirely sure that you understand the difference between chaos and randomness.

    If chaos is governed by natural law, is it really chaos?

    Yes, in the sense that chaotic states are local. For example, in an explosion the molecules fly about in a random manner. Science can predict the extent of the blast wave, the heat produced, the type of damage it will cause, and even the shape of the blast, but not where individual molecules will go.

    In a natural system like a forest, the leaves of the trees fall to the forest floor in the autumn in no particular geometric pattern, but which trees shed their leaves first is part of the natural law. Chaos is partly a way of looking at things.

    It's a big, bold, and unsupported statement for us to say that anything in nature is "governed" by ... whatever. We have made the subtle transformation from "observations of nature" to "laws of nature". But we don't know they are laws. All we know is that, so far, here, from what we have observed, this thing seems to always follow that thing. No criticism to you personally, just saying - we have overstepped, imo, to declare anything a "law" in nature.

    Yes. Chaotic behaviour is simply the result of small variations having significant impacts on a system. Chaotic systems are unpredictable but not necessarily random.

    A good example is a string pendulum. If you swing a pedulum so that it follows a circular rather than linear path, what you'll find is that the path it takes becomes unpredictable. It is obeying the laws of physics, but various factors are changing. There is twisting and tension in the string, changes in air currents, humidity and pressure changes, and so on. However, the behaviour isn't random. The pendulum will eventually stop and there will be limits to how far it can swing. It can't go left then right in an instant of time or zigzag in straight lines.

    So the pendulum is following the laws of physics. The behaviour is constrained to certain possibilities. But we can't predict what the behaviour will actually be!

    Yes, it is, but there is randomness as well because of quantum mechanics. Do Google or Bing searches on the Golden ratio, chaos theory, the butterfly effect, fractals and entropy. . Natural laws = laws of physics and thermodynamics. At atomic and subatomic scales of size, God DOES "...play dice with the Universe...". Humans are how the Universe observes itself. We exist right where the microscale an macro scale processes of the Universe intersect and have a union. I am.paraphrasing several scientists. Those pesky Venn diagrams in math and science DO apply to reality and the real Universe.

    Kind of, yeah, but it's more just mathematical laws than physical natural laws.

    I'll try to explain what chaos is about so you have some understanding of what's going on.

    Consider a scenario where the ladder is perfectly balanced, so that it is standing straight up. In this scenario, the ladder is in a "critical state", where any change whatsoever can cause it to fall one way vs the other and you don't know which way it will fall. However, once the ladder starts toppling, you know how the remainder of its fall is going to play out.

    "Chaotic" systems are ones where they are always in critical states; it's like a ladder that is always teetering even when it's moving. You never really know how they are going to play out because tiny differences at any point will cause major differences in its motion at later times.

    One of the simplest examples of a chaotic system is a double pendulum, which is basically just two pendulums with one attached to the end of the other. This situation is kind of like a ladder attached to the end of another ladder, but with no ground for them to hit a final resting state. In a way, this creates a way for the ladder in the initial scenario to always be in that teetering vertical state but maintain that state while its not vertical and also while its moving.

    I've linked a double pendulum simulator in the sources. If you play around with it, you'll find that the motion of the pendulums is highly erratic and difficult to predict.

    You can pause the simulation, and make it so both pendulums are standing straight up. If you do this a couple of times and let the simulations run, then you'll find that the motion of the pendulum will vary radically over time. This is because tiny errors made in trying to get them to both stand straight up will have their effects magnified over time (this is basically a signature of mathematically chaotic systems).

    However, if you did get them in the EXACT same positions for two different runs, then those runs would pan out exactly the same. The point being that "chaos" isn't stemming from a lack of rules or anything like that, but stemming from minor differences manifesting major differences over time in certain scenarios and our inherently imprecise knowledge of the world around us.
