Daniel has issues of accuracy as well as the use of Greek words proving to most scholars that the book was written after the Greeks conquered Persia. Probably much later like around the 2 BCE for the writer could not even get his history right and named The wrong guy as king of Persia and got his father mixed up for his son or vice versa can’t remember which.
Anyway the book of Daniel has lots of issues such as the statues with different mental representing different powers. Well first off the order of the metals down to the feet represent different ages of man being created in the Greek pantheon. Gold for the original men created by I believe Kronos called the golden age. After Zues creates the rest of the men on type after another until the legs of Iron men that become so strong they do away with the gods according to Greek myths. This is just more conclusive evidence that this writting we Call Daniel was heavily influenced by Greeks.
