The idea emphasized throughout the article is that all matter was created billions of years ago. The article explains that the building blocks of matter, such as quarks and electrons, were formed during the Big Bang. These building blocks eventually combined to form the first atoms, which were mainly hydrogen and helium. Stars played a crucial role in the creation of heavier elements, including those essential for life on Earth. So, all matter, including our bodies, originated from stardust.
