In present-day terms, as of January, 2014 over 7000 different languages exist on the globe. The Bible has been fully translated into over 500 languages with some portion of the Bible in over 2500 languages. Linguists will note that the structure of a language devolves and morphs into other less structured forms. English has degraded in structure and form from its inception. In fact all of the languages deriving from Latin are less structured than their Latin roots. This effect is expected first from the propensity of structure to become less organized as entropy creeps into a structured system. It is expected second from the curse of Babel, that the nations remain divided.
The propensity of the human mind to naturally follow a path of communication appears in stranger forms, such as the Kennedy Twins a form of idioglossia where they developed their own personalized language that nobody understood but them. This not related to their being twins, but being isolated and in need of a communication mechanism. Generally an infant's language will ultimately align with the primary language of its mother.
The Piraha people in Northwest Brazil have a language that is devoid of the concept of numbers. They can accommodate immediate comparison (conceptually a "2") are inherently unable to correlate numeric concepts beyond the capacity of three or more. It is completely missing from their language.
Supernatural Aspects of Language
In Acts 2:6 we read that the apostles were able to speak in their own language while all those present actually heard the words in the own various native languages. At the Tower of Babel, all people speaking a common tongue were suddenly cursed with various tongues. This is because all language is supernatural. It is a supernatural gift from the Creator for mankind's communication with God and with other humans.
We are also informed that the gift of tongues (languages) is for use before unbelievers 1 Corinthians 14:22 as a sign. And that the coming "son of perdition" 2 Thessalonians 2:3 will come to power 2 Thessalonians 2:9 with signs and lying wonders. As signs are associated with language, theologians have speculated that the son of perdition will perform language-based miracles just as he will change times and laws for his own glory Daniel 7:25 .
Some Christian believers have attempted to deliberately separate common language from supernatural language, but this is usually practiced in a manner that is very deliberately outside of Scriptural rules for doing so. The Bible (1 Corinthians 14 aforementioned) requires an interpreter and that it be a testimony to unbelievers. Conversely, these believers practice it as a testimony to other believers only. In addition, these practices are identical to pagan ecstatic speech  and the Corinthians practiced a form of demonic ecstatic speech. These practices include a deliberate "heaving" hyperventilation during a worship service, either initiated by the worship minister or individual persons, which fills the body with oxygen and creates an oxygen-induced delirium or oxygen high that can ultimately result in verbal babbling and convulsions. The believer is convinced that the experience is "real" but has no understanding of the words spoken.
In The Genesis Record, Henry Morris points out the theologically-accepted view that the phrase "toledoth" - these are the generations of - separates the book of Genesis into various diaries, compiled and edited by Moses under the authority of God's spirit. Each diary is then punctuated by a "signature" phrase "these are the generations of" which terminates the diary and begins a new one. For example, chapter 5 begins "the book of the generations of Adam" and mentions the word "book". Moses would have no reason to use this word unless he was in possession of the written document as penned by Adam. The words after this offer a genealogy and Adam's death, but Adam would not have recorded his own death. We also note that Genesis 25:12 ends the diary of Ishmael, where Genesis 25:19 ends the diary of Isaac, neither of which are mentioned afterward except in genealogies. An important point is that in Genesis 25:11 Isaac records Abraham's death, immediately followed by Ishmael's diary and the signature of his own. We would expect Ishmael and Isaac to have traded records at Abraham's funeral.
This diary mechanism explains why Genesis chapter 1 and chapter 2 seem to be different creation accounts, when they are actually accounts from different perspectives. The first one, signed by the Creator "these are the generations of the heavens and the earth" is from a different perspective than the following diaries.
This also generally sets aside the "JEDP" theory of Genesis construction.
What this also strongly implies is that the first written and spoken words in sight and hearing of Adam were "In the beginning.."
The City of Ebla, dating prior to 2500 BC, has a library of 17,000 stone tablets in both Cuneiform and a Semitic language called Eblaite. It is presumed that the Eblaite proto-Hebrew or paleo-Hebrew is a candidate for consideration as the oldest written language known to man, the original language of pre-Flood humans and the language used at Babel prior to the confusion of languages.
Complex written and verbal languages preceded the most ancient post-Flood civilizations such as Sumeria and Babylon, rendering their "flood legends" and "creation myths" to be derivations from the original pre-Flood account rather than the other way around. The book of Job is considered the oldest book in the Bible in the post-Flood era, dating back to over 2500 BC in its penning and setting.
The explosion of language and culture in Mesopotamia (dated roughly 3000 BC) coincides with the confusion of languages at Babel (in Shinar, in Mesopotamia).
The Indo-European languages consist of Latin, Greek, Hittite, Sanskrit, French, German, Latvian, English, Spanish, Russian and dozens of others, many have become extinct meaning no known native speakers are alive today. What is called Proto-Indo-European (PIE) is the lost ancestral language from which the Indo-European languages ultimately derived from.
- Main Article: Tower of Babel
The Tower of Babel (Hebrew: מגדל בבל, Migdāl Bāḇẹl; Arabic: برج بابل, Burj Babil) (built Built::Tammuz 1762 AM) was the first building project attempted by humans after the global flood. The approximate date of its building is given by James Ussher, who in The Annals of the World cites Manetho's Book of Sothis, as translated by Georgius Syncellus, as stating that the Babel Incident took place five years following the birth year of Peleg.
