First of all, are you kidding me? You're actually sourcing your information from a creationist website? :facepalm: I will not partake in a scientific discussion with apologetic pseudoscientists who deceitfully manipulate scientific knowledge to suit their own agenda.
Second, the article fails to mention that the ways by which elements heavier than iron are formed are endothermic nuclear fusion and slow/rapid neutron capture processes. These are well-known processes in nucleosynthesis, none of which are discussed, not even briefly.
Third, and I don't know if you noticed this, but that quote proves the opposite of what you're saying. You said:
Nemesis-301 wroteand secondly, he is assuming that the elements found on earth are the same ones that exist in the stars... nobody knows that...
And yet:
It is suggested that the elements heavier than iron formed as a result of supernovae exploding.
Where do you think supernovae come from? And guess what, we're also able to detect the elements present in supernovae and their remnants using spectroscopy. And yes, the hydrogen atoms that make the earth as well as our bodies are as old as the universe itself.
