We talk with different languages in this world. But all these languages have one common amazing thing : the complexity.
When you see how our "linguistic" system works when we are speaking (in any language) you will be stupefied by the number of moves that we do with our tongue, teeth, lips and throat to produce a number of sounds : letters or phonems. And the amazing way how skillfully we join these sounds one to another to make words. And how we use this faculty of designating every object around by a sequence of sounds : a name.
All this is amazing !
I can say it's impossible for the first humans on earth to invent such a complex system.
A human being can't create a language. All the theories saying that the man found himself on earth dumb (mute) an then he created his own language after hearing the sound of animals and nature, all these theories seems to me superficial and irrealistic with regard to the complexity of the process of talking. I'd rather say that the language is innate with the first human on earth.
I know it's easy to derive a language from another (english,french from latin...) but it's quite unrealizable for a human to invent a language from nothing.
The idea I support is that the language is innate (in the first human mind) :
The first human(s) spoke one language : the original language, and his descendants derived from it the different languages we speak today. Or the first human(s) spoke a group of original languages, and from them we derived our languages, and I have three arguments for that :
1) My first argument is the complexity of the speaking process.
2) My second argument is an interpetation(my interpretation can be wrong) of some verses in the qur'an :
1 ـ وعلم آدم الأسماء كلها[ البقرة:31].
002.031 And He taught Adam the names of all things; then He placed them before the angels, and said: "Tell me the names of these if ye are right."
2 ـ الرحمن* علم القرآن* خلق الإنسان* علمه البيان[ الرحمن:1 ـ4].
055.001 (God) Most Gracious!
.002 It is He Who has taught the Qur'an.
.003 He has created man:
.004 He has taught him speech (and intelligence).
3 ـ اقرأ باسم ربك الذي خلق* خلق الإنسان من علق* اقرأ وربك الأكرم* الذي علم بالقلم* علم الإنسان ما لم يعلم*[ العلق:1 ـ5].
096.001 Proclaim! (or read!) in the name of thy Lord and Cherisher, Who created-
.002 Created man, out of a (mere) clot of congealed blood:
.003 Proclaim! And thy Lord is Most Bountiful,-
.004 He Who taught (the use of) the pen,-
.005 Taught man that which he knew not.
3) My third argument is the conformity between the speaking organs (mouth, tongue, lips, teeth..)
and the speaking process(the language) : Allah who created our speaking organs, created also the language that fits to them.
I have to say that it's not explicitely the Islamic point of view, but it's the point of view of a number of muslim scholars an scientists, one of them is Dr. Zaghlool Najar.
if you understand arabic here is an
article in arabic of Dr.Zaghlool in the Ahram egyptian news paper. I'm sorry I don't find the english version of his article.
