On the southern island of the Andaman Island chain in the Indian Ocean is the language known as Jarawa.  There are 300 speakers of Jarawa.  No one else in the world knows Jarawa and no Jarawa speaker knows any other language.  Every single Jarawa speaker is a monolingual.  The government of India (which governs the Andamans) supports them in maintaining their utter privacy.  There are no books on Jarawa and no way to learn Jarawa.  I would have to say that Jarawa is the least known language on the earth.

English is an almost universal "trade" language.\n\nThe Navajo language is THE most difficult.  It's been said, "If you don't grow up learning and speaking Navajo...fergit it, you'll never learn it!"

The earliest human language was in Africa about 100,000 years ago.  We have, of course, no records of that language since writing was not invented for another 95,000 years.\n\nAnd to correct errors in previous answers:  Latin and Greek are NOT the ancestors of the world's languages.  Latin is the ancestor of about 20 modern languages of Europe and Greek is just the ancestor of Modern Greek.  Old Chinese is the ancestor of the half dozen Chinese languages.  There are about 200 Indo-European languages and about 6000 languages in the world, so most of the world's languages are NOT Indo-European.

It depends on how you separate languages from dialects. There are many different counts, but the range is between 4000 and 8000. A number of 6000 is probably about right for most purposes. If there were 6 people in the world and each spoke 1000 languages, one person would live in the Americas, one person would live in Europe and Asia, two people would live in Africa, one person would live on all the islands of Asia and the Pacific, and one person would live on the island of New Guinea.\n\nIf you count second language speakers as well as native speakers, English is the most widely used language in the world.  Mandarin Chinese (Putonghua) has the most native speakers.

I don't think anyone knows for sure.  Many thousands.  For example the Inuktitut language (of northern peoples formerly called Eskimo) might be counted as one language.  However, there are several different versions - at least three in Canada, Alaska is probsbly different again, Greenland different again, etc.  At best there are estimates about the number of languages.

Sign Language, of course:)\n\nBy the way, no language is any more difficult than another for it's respective native speakers.\n\nChinese may be difficult for a native English speaker to speak, but a baby learns it as easily as it would English.

'cause you think so, that English is the first popular language.\n\nIt's matter of the sharing, in this mean, most popular one would be Chinese, spoken by 17% peoples of the  population in this world. English share is 9%. And 8% of the spoken majority mainly in India, means Hindi and Urdu... Spanish is 6%.

I think Latin is the most difficult language to learn because people don't use it a lot nowaday.\n\nLatin is a member of the Italic branch of the Indo-European family of languages. After the decline of the Roman Empire it continued to be a medium of communication among educated people throughout the Middle Ages in Europe and elsewhere, and remained the liturgical language of the Roman Catholic Church until the reforms of the second Vatican Council (1962-5); it is still used for scientific names in biology and astronomy. The Romance languages are derived from it. (The New Oxford Dictionary)
