The following factors that have nothing to do with the existence of living matter on the earth are A, the distance between the sun and the earth B, the cosmic environment C, the volume and mass of the earth D, and the autobiographical direction of the earth. The answer is D: It has nothing to do with the birth of life.

A: This is definitely the most obvious. If the earth is so close to the sun like mercury, the temperature will reach several hundred degrees Celsius during the day, which is enough to melt metal and it is impossible to breed life.

This point is easily overlooked. One factor is the position of the solar system in the Milky Way. The earth is the only planet we know that there is life, because our little solar system was born in the right place in the galaxy. If we were closer to the center of the galaxy, we would all cease to exist. The center of the Milky Way galaxy is full of supermassive stars, which are extremely radioactive, so life can't survive in that environment at all. And if it is farther away from the galactic center, there is too little material here, and the stars formed are smaller than the sun, which can't meet the requirements of life.

C: The mass and volume of the earth are also important. If the gravity of the earth were as strong as Jupiter, life would certainly not be born. Because the weather on the massive planet is extremely extreme, due to the storm under the dense clouds, the temperature can reach thousands or even tens of thousands of degrees Celsius, and life cannot be born in such extreme environment.

D: If the rotation direction is opposite, then the sun just rises in the west and sets in the east. It doesn't have much impact on the birth of life (although there is also a point that the sudden reversal of the earth will confuse biological habits now). If you must choose an irrelevant factor or a factor with the least influence, that is D.
