I guess at no point in the suns Billions of years of existence could it have had a coronal mass ejection large enough to reach earth, thus depositing
TRACES of helium-4.
Buy the way, Degradation of of some of the heavier elements produce this

Helium-4 (42He or 4He) is a non-radioactive and light isotope of helium. It is by far the most abundant of the two naturally occurring isotopes of
helium, making up about 99.99986% of the helium on earth. Its nucleus is a boson and an alpha particle, having two protons and two neutrons. Alpha
decay is a common decay mode for many radioactive isotopes. In fact, alpha decay of heavy elements is the source of most naturally occurring helium-4
on earth. Helium-4 is also a byproduct of nuclear fusion in stars.
When helium-4 is cooled to below 2.17 kelvins (–271 °C), it becomes a super fluid, with properties that are very unlike those of an ordinary
liquid. For example, if helium-4 is kept in an open vessel, a thin film will climb up the sides of the vessel and overflow. Another name for this
property of Helium is Rollin film. This strange behavior is a result of the Clausius-Clapeyron relation and cannot be explained by the current model
of classical mechanics nor by nuclear or electrical models; it is only understood as a quantum mechanical phenomenon.
