That's an odd conclusion. You'd expect a very old star to have
had enough time to make lots of heavier elements.
You'd expect a Leprechaun to have a pot 'o gold at the end of the rainbow.

Nobody has a clue what was happening a billion years ago.
You are wrong. From observations we have a pretty good clue what happened
*elsewhere* (ca. one billion light-years away) ca. one billion years ago.
For example:

Y'all are clueless as to what is happening in front of your own faces right now.
That much is true, because we cannot observe what is happening right now (at
the same time) as light and gravitational waves take time to propagate to
us. However, their speed is very fast; in vacuum, the speed of light is
299 792 458 m/s, and apparently that is also the speed of gravitational waves.
