Rather sure you noticed have seen this posted as a reply to another of your posts but this video does a better job of answering this question so for those that did not notice your other posts. . .

"I know it is subject to, very complex physics laws" au contraire, the foundations that establish the formation and evolution of the sun, from a layman's point of view, can be distilled so the simplest of minds can gain an understanding of the process.

As you appear to be evoking a (what I am going to guess, as you appear to be promoting the sun have a sentient meaning you would call) "Spiritual" relationship with the sun and "heavens?" really, heaven?

The simple answer to your implied question placed in the guise of your metaphorical blathering
is this:

We evolved to be best suited for our environment. To love our environment would be beneficial. Those that hate or dislike the the natural world would be less likely to thrive as emotional happiness is a factor in physical health.

We must all remember that the warmth we feel from the sun is ultra-violet radiation, a leading cause of skin cancer, and other degenerative diseases. The sun bombards our planet with doses of radiation that would be lethal to organic life as we know it, were it not for the ozone layer and the magnetosphere. That which gives life, just as easily kills. In the words of Robert Green Ingersoll:

“Nature, so far as we can discern, without passion and without intention, forms, transforms, and retransforms forever. She neither weeps nor rejoices. She produces man without purpose, and obliterates him without regret. She knows no distinction between the beneficial and the hurtful. Poison and nutrition, pain and joy, life and death, smiles and tears are alike to her. She is neither merciful nor cruel. She cannot be flattered by worship nor melted by tears. She does not know even the attitude of prayer. She appreciates no difference between poison in the fangs of snakes and mercy in the hearts of men. Only through man does nature take cognizance of the good, the true, and the beautiful; and, so far as we know, man is the highest intelligence.”
The Gods, 1873

Feelings exist. Objective reality exists. They don’t always tell the same story.

To the contrary, we conform to it.

The sun is my shepherd, I shall not want. It warmeth my face, it calmeth my soul.

I mean that is one way to look at it.

I will admit that on one level, that it's just in fact a raging ball of blazing helium that our planet orbits, is not comforting or sexy. However ... from another perspective that is fascinating and awesome in its own right. Still ... it's not reason to anthropomorphize and then glorify the sun. One should always be in touch with reality, which is that the sun lacks sentient purpose.

There's no "stone." It's a star not a rocky planet. It consists of gas and provides heat by fusion. It doesn't go to the other side; the earth rotates. None of this is particularly complex physics, but basic astronomy.
