They know there's really only one way that the heavy elements (that is, pretty much anything other than hydrogen and helium) can be created, and that's through the immense pressures that exist within the interior of a sun. Many stars (what I believe they call 1st-generation stars) have only hydrogen and helium, but when they examine the remnants from, say, a supernova, they find the rest of the elements.

Thanks. When they analize our bodies, they always say they find this much per cent of gold, this much copper, and so on, etc. It then is more evident from the micro biology where we come from I guess
