You don’t need to be “smarter”, you just need to have a basic understanding of evolution.
Two geographically separate populations that at one time were members of the same species later may have diverged into two different species. Since the process is gradual, there is no particular point at which it is possible to say that the two populations have become two different species. [1]
If “there is no particular point at which it is possible to say that the two populations have become two different species”, there is no point at which a specific first individual member of the new species existed.
Evolution, and speciation, occurs at the level of populations, not individuals.
Analogously, we are also unable to point to the first speaker of French – as the divergence from Latin was likewise gradual.
That somebody would consider themselves qualified to criticise evolution, let alone claim expertise in a subsection of population genetics, without understanding this very basic principle, is problematical in the extreme.
This level of basic misunderstanding Paul, not “religous ferver[sic]”, is why Creationist apologetics has zero scientific credibility.
