Is it truer to say "the hydrogen and oxygen on our Earth today are the same [...] 5 billion years"?

  If those hydrogen and oxygen atoms had not previously been bonded into H2O, you would have to say this is “new” water, right?

    What if they bonded with different atoms? To get truly duplicate water it would need to find its partner(s, who knew water was poly), I suspect the odds are low :-)
