If you want to know the record holder for the easiest language in the world, then you're in the right place. There is no real answer to the question "what is the easiest language in the world?" Many languages claim this title. Esperanto, English, Italian are said to be the easiest, because of their simple grammar without many irregular rules. Also note that Esperanto is a constructed language, which means, it was made specifically to be easy to learn and eventually become a global language, so it has an advantage over the other human languages.
However you need to consider other factors that might make a language especially easy for YOU, for example whether a language follows a logical pattern in its grammar. In English, there is a general rule for creating plurals, adding "s" or "es". In some other languages, there is no difference between plural and singular. Also you need to consider how the new language you're trying to learn is different from your native language. An Spanish speaker will find Itlian easier to learn than a person whose native language is Korean.

Note that the biggest land animal in the world is the African Elephant. African elephants males stand 3.2–4.0 m (10–13 ft) tall at the shoulder and weigh 4,700–6,048 kg (10,000–13,330 lb), while females stand 2.2–2.6 m (7.2–8.5 ft) tall and weigh 2,160–3,232 kg (4,800–7,130 lb). The African Elephant is larger than the Asian Elephant. These mammals have very strong social bonds and live in family groups headed by a female (called a cow). Males (called bulls) occasionally join the group. Elephants are excellent swimmers. Elephants have few natural enemies except man, and they are in danger of extinction due to loss of habitat and poaching (they are killed for their ivory tusks).
