Two links on the from hydrogen till now part:
https://en.wikipedia.org/wiki/Metallicity Don't be scared by the math it is all basic simple observed percentages dressed up to look impressive and overly complicated (dam scientists just love to LOOK super smart more than anything don't they?), just ignore the parts you don't get.
If the elements themselves are too confusing, start here https://en.wikipedia.org/wiki/Chemical_element
Then move on to https://en.wikipedia.org/wiki/Geochronology and https://en.wikipedia.org/wiki/Radiometric_dating.
Actually pretty simple, but very interesting stuff largely overlooked by many pop shows who tend to focus on bleeding edge science.
