I'm going to tell you how the Sun works.

The established scientific model is the Sun is ludicrously outdated and contradicted by almost every piece of observable evidence we have from it.

Currently, science believes the Sun to be an enormous thermonuclear explosion that is constantly burning through fuel that it makes up its mass. Initially we can throw the thermonuclear model out because the Sun has a cyclical output system of energy output cycles. It is impossible in current physics for a thermonuclear reaction to display as sort of cyclical pattern.

The temperature gradient travelling away from the Sun is anything but linear. Some areas are millions of degree hotter than others that are closer in distance to the body of the Sun. These can and do fluctuate considerably as you travel away from the Sun.

The interior of the Sun is an order of magnitude cooler than the surface. How, in a thermonuclear reaction is this at all possible? It isn't is the simple answer.

What is the Sun?

The Sun appears to be an enormous magnet and almost all phenomena we observe from the Sun is magnetic interactions. What it is powered by I will elaborate on in a bit.

The Sun projects several magnetic fields of varying strength out from it. The largest is the heliosphere, which extends far out from the solar system. This 'bubble' is the primary field that interacts with the rest of the universe. I call it a bubble because in some ways that's what it is. Every other star puts out it's own magnetic force which compounds into the magnetic soup or ether that permeates the entire universe. The collective force of this is quite large and bears down on everything in the void. Think of the pressure at great depths under the sea, it is the same concept in the void of space with magnetic force. The initial resistance the Sun has to this magnetic 'pressure' is the edge of the heliosphere.
Try to visualise the void, permeated by the magnetic force of all stars in the universe and the pressure that force would exert on a magnetic field in deep space. The Sun pushes out against this force and the limit of that resistance is the outer edge of the heliosphere. This barrier keeps out a large amount of the energy from the rest of the universe entering into our solar system. Of course some energy still breaches that barrier but no where near as much as if it was absent.

The next significant magnetic barrier of the Sun is the surface of the Sun. The surface can be thought of as a reverse event-horizon. This is the barrier where all the energy from space interacts with the magnetic field projected by the Sun, the result of that interact is magnetic discharge which we see as fire and feel as heat. The surface of the Sun is the energetic reaction between the magnetic field of the Sun and the cumulative magnetic force of the rest of the universe. Of course since both of those energies are extremely high, the reaction is significant. This is the reason that when viewed through modern equipment, solar flares don't look like giant tongues of flame, they look like magnetic field lines. It is also the reason why the inside of the Sun, as seen through sunspots is far cooler than the surface, something that is impossible in the thermonuclear model.

This further explains what we think of as 'climate change'. Because the Sun has a cyclical energy output and we are approaching a solar minimum in which the energy output of the Sun is lower, the force resisting the rest of the universe is lower, which means more energy from space will seep through the heliosphere. More energy in the heliosphere means more energy in our 'bubble' and more pressure on the Earth's magnetic field, which is also dropping in strength. This means more energy is going to enter our atmosphere causing more extreme weather events.

So WHAT is the Sun?

It is obviously not a ball of burning gas. While that may seem like an idea from the surface of the Earth, with more modern measuring equipment we must abandon that theory because almost literally everything about the Sun negates it. What I believe the Sun is is a living being. Magnetic fields are created by electric current, they are also created by every living thing we observe. Everything that is conscious creates a magnetic field of some type. Rocks, plants, animals, humans. Further up that chain we see planets and Suns also with their own magnetic fields. What I believe the Sun to be is a living being at least two orders of magnitude up from human beings. Our magnetic is relatively weak but it is present, the Sun's is so strong it interacts with the rest of the universe. What the interior body of the Sun looks like I have no idea, same with the Earth. What it thinks, or does, I also have no idea. But when the ancients referred to the Sun as our God I think they were far more correct than we give them credit for. I don't believe it was a primitive 'this thing rises in the morning and gives us heat and light so worship it' notion is valid. For one it must be completely thrown out if there is evidence of civilisation prior to what we believe to be the beginning of human history, which is literally everywhere on the planet in the form of megalithic structures. Primitive worship of the Sun could only be valid if our ancestors were simple cavemen. If they were the remainders of a previous civilsation that was destroyed and forced back into a hunter-gatherer lifestyle than the knowledge of what the Sun is could have remained from that previous time.

This also provides some interesting implications as to the former position of the planets in our solar system. If the energy output of the Sun was significantly different from its current levels, than the magnetic web of the planets would be in a different order. If the planetary bodies themselves can somehow alter the strength of their magnetic fields than one of them could have been the dominant force in the solar system for a period of time. This all of a sudden makes the numerous myths about Saturn once being the largest celestial body in the sky no longer unrealistic.

In summary: The Sun is potentially a living being that generates an enormous magnetic field. We see the interactions of this magnetic field with the energy from the rest of space in our heliosphere and on the surface of the Sun.
