Here's why:
* Capitalization Rules: In English, only the first letter of a sentence, proper nouns, and specific instances like titles are capitalized.
* Lowercase Usage: The letter "e" is used in lowercase for the vast majority of words, such as "the," "eat," "earth," and countless others.
* Exceptions: Some words like "England" or "Europe" have a capitalized "E" because they are proper nouns.
