Probing the Earth's core directly is impossible, so the only way to know more about the origins of our planet is to observe what comes out.

Researchers at the California Institute of Technology and Woods Hole Oceanographic Institution turned to 62-million-year-old Arctic rocks to find compelling evidence that the core of the planet has been leaking helium since the time of Earth's formation,
Nearly 4.6 billion years ago, a nebula gave rise to our Sun, Earth, and other planets. During the early stages, the core of the Earth is believed to have ingested a lot of helium gas as well. Since it is an inert gas and light in nature, it is easy for helium to escape through the cracks in the Earth's mantle and into the atmosphere.The reason we do not see a lot of helium in the atmosphere, too, is due to its tendency to rise higher and escape into space.
Not only were the helium levels 50 times higher than the atmosphere, but they also belonged to larger amounts of Helium 3 yet measured in terrestrial igneous rocks, in olivines from Baffin Island lavas. We argue that the extremely high-3He/4He helium in these lavas might derive from Earth’s core.
