The video did not explain why the sun is a low entropy source. I found this explaining what I am sharing with you:
So, the sun is a low-entropy source of energy, and Earth (and everything on it) increases that entropy as it uses and then reradiates that energy. This process is entirely consistent with the second law of thermodynamics.
The relationship between light frequency and entropy comes from the fact that entropy is a measure of disorder or randomness. High-frequency light, such as ultraviolet or visible light, is more ordered and less random than lower-frequency light, such as infrared or microwave light.
This is due to how light is structured. Light is made up of particles called photons, and each photon carries a certain amount of energy. The energy of a photon is directly proportional to its frequency: higher-frequency photons carry more energy than lower-frequency ones.
So, if you have a fixed amount of energy to distribute among photons, you can do so in many more ways (i.e., with higher entropy) if you use low-energy, low-frequency photons. That's because you would need many more of them to carry the same total amount of energy.
On the other hand, if you use high-energy, high-frequency photons, you would need fewer of them to carry the same total amount of energy. There are fewer ways to distribute the energy (i.e., lower entropy), so this arrangement is more ordered and less random.
Therefore, high-frequency light is considered a lower-entropy form of energy compared to low-frequency light, because the energy is concentrated in fewer, more energetic photons.

Laymen to the extreme but, didn't it? The thing about the low entropy of the universe near the big bang, gravity naturally bringing things together, and such?
