What's the most widely accepted position on this. Was the Big Bang a

completely devoid of any matter other than the point at which the Big
Bang occurred?

This quote is new to me:

Big Bang Nucleosynthesis
"Most lithium and beryllium is produced by cosmic ray collisions
breaking up some of the carbon produced in stars."

I thought most Lithium was produced in the Big Bang? And that all of the
Lithium we have now is all that we'll ever have.
