The name in Europe isn't the original interpretation. Ea was the original name of the Samaritan God Enki. There was Enki and Enlil. Enki was originally called Ea two thousand years before the Jewish Religion was even formed.
Looks like a typo. Like where's the rest of it? And is it ee-uh or ay-uh? For ee-uh, I prefer Iah, and for ay-uh, I prefer Aya. If the real pronunciation is just "ee", then I prefer Esa. I mean, give the poor child a name, not a letter, huh?
