A Tale of the Origin of the Earth's Elemental Composition

Modern science can explain everything. How and when the Universe arose, how the solar system and the Earth formed. However, it cannot answer the simplest children's question. Why is the composition of the earth's crust different from the composition of the stellar matter from which the Earth was formed? It is clear that some nuclear reactions must be responsible for this phenomenon. However, according to existing ideas, no nuclear reactions are possible in the conditions that existed on Earth. Low-temperature nuclear reactions are possible, but this direction is considered pseudoscientific. It is possible only in a fairy tale to tell about the phenomena responsible for the change in isotopic composition. Smart nuclides are to blame for everything, which, when meeting, agree to transfer several nucleons from one nuclide to another. As a result, new smart nuclides with a changed number of nucleons appear. Such transfers are responsible for the transformation of the isotopic composition of stellar matter into the isotopic composition of the earth's crust. As required in a fairy tale, many pictures and short videos illustrating the process of such a transformation are presented.
