The assumption of the argument is that the condition adopted by nature to make the F is the same as that used in the lab.
But if the naturally occurring F is a different form from that made in the lab, then the condition to form the naturally occurring F might be different from that to form the synthetic F. Thus, the conclusion is doubtful.
