It is difficult to agree with Psammetichus because language is constantly evolving and changing due to various factors such as cultural interactions, migrations, and technological advancements. There is no singular "original human language" as languages have developed independently across different regions. Additionally, the complexity and diversity of languages makes it challenging to pinpoint one as the original.

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.

The origins of language are not definitively known, but early forms are believed to have developed among early humans to communicate and cooperate with each other. It is thought that language evolved gradually over time through a combination of social, cultural, and biological factors. Linguists and anthropologists continue to study the development of language to better understand its beginnings.

The Greek cities of Asia Minor became restive under Persian rule, and the following year rose in revolt. This was suppressed and this brought in the cities of mainland Greece, leading to 50 years of sporadic warfare until the Persians gave up and left the cities to their internal fighting of each other.
