I've heard this question asked in a YouTube video ad (many times), as though this should be hard to believe. Whats amazing is that today, birds talk!

A serpent talking is no more astounding than a bird talking. So keep in mind that ravens, parrots, dogs, seals (e.g., Hoover), elephants, etc. can speak using human language. The question for the evolutionist is, why would they be surprised at all, given their worldview? They should not even be surprised that someone resurrected from the dead, given that many other things came to life where there was no life and random/chance events produce entire solar systems.
