Why is it difficult to agree with psammetichus the phrygian must have been the original human language?

It is difficult to agree with Psammetichus' theory that Phrygian was the original human language because there is limited evidence to support this claim. Linguistic studies and historical research suggest that language evolution is more complex and diverse, making it unlikely that one specific language was the universal origin for all human languages. Additionally, the diversity and variability of languages across different regions and cultures make it challenging to pinpoint a single language as the original.
