As for why it is an answer rather than a question, because many top scientists in history have had similar explanations, such as Newton and others, which naturally triggered theological thinking from a scientific point of view, that is, on the basis of a large number of scientific deposits, everything is not accidental, absolutely not accidental, but something created everything and made everything run according to strict laws!
As for how to simply understand:
Take crows for example. The crow suddenly found a water dispenser. As long as he taps the water dispenser with his mouth, water will flow out. In the crow's eyes, the water dispenser is unknown to him. All he knows is that he can fetch water. He will never know that this thing was made by human beings (creatures more advanced than crows), and he will think that it is a good thing that fell from the sky.
Therefore, if we compare human beings to this crow, we can see that the sun rises in the east and sets in the west every day, and we can live and produce according to the heat and light provided by this sun. We will think that this is also a godsend, but why can't the sun be created by creatures more advanced than humans?
So the end point of science is theology, which is not an absurd conclusion, but a very rigorous point of view. Mr. Yang's statement is not absurd, but he is seriously talking about science, even the origin of everything!
