Uhh again the "only human has soul" argument. What means by soul, please define this word, philosopher. Does bird know language grammars indicate that soul exist? Does fish can do arithmetic up to 5 show that their soul exist? Does elephant do funeral to their dead fellow show that there is a soul? Can this humancentric ideology just go away?
