For most of Egyptian history the language written in actual hieroglyphics or in its cursive counterpart, hieratic, was the literary language initiated in the XII Dynasty (1991-1786) of the Middle Kingdom. \nThat is called "Middle Egyptian." In hieroglyphics or hieratic, therefore, one is only likely to encounter either Middle Egyptian or the earlier literary form of the language, Old Egyptian, the language spoken in the Archaic Period (I & II Dynasties, c. 3100-2680) and the Old Kingdom (III-VI Dynasties, 2680-2159). \nWhile Sir Alan Gardiner, in his great and indispensable Egyptian Grammar [Oxford University Press, 1927, 1964], says that Middle Egyptian was "possibly the vernacular of Dynasties IX-XI," Stephen Fryer has brought to my attention recent research to the effect that the literary language of the XII Dynasty was in some measure an artificial attempt to return to the forms of Old Egyptian. Since the political project of Egyptian Kings was always to restore things "as they were in the beginning," this is not surprising. Middle Egyptian, therefore, may have something like the status of Classical Sanskrit, which restored and fixed the forms of the language of the Vedas but could not undo all the changes that had already occurred in the spoken language.\n\nAlthough Middle Egyptian became the literary and written language, the spoken language continued to change. The language of the New Kingdom (XVIII-XX Dynasties, 1575-1087) and much of the Third Intermediate Period (XXI-XXIV Dynasties, 1087-715) is then called "New" or "Late Egyptian." By the Ramessid Period (Dynasties XIX & XX), most hieratic documents are in Late Egyptian. \nThe best evidence of the pronunciation of Late Egyptian, however, is from the documents found in the diplomatic archives of Amenhotep III and Akhenaton at Amarna, for these documents were kept in Akkadian, not in Egyptian. Akkadian was the diplomatic language of the day, essentially the same language as its two daughter languages, Babylonian and Assyrian; and its system of writing, cuneiform, represented vowels. Late Egyptian grammar also begins to be revealed by hieroglyphic inscriptions during the reign of Akhenaton, when the spoken language briefly replaced Middle Egyptian. Thus, while Old and Middle Egyptian did not have a definite article ("the"), Late Egyptian does, p3, later pronounced "pi" or "pe" in Coptic -- though now it appears that this change had already begun in the actual spoken language of the XII Dynasty.\n\nFollowing Late Egyptian are two stages of the spoken language, Demotic (c. 715 BC-470 AD) and Coptic (c. 400 AD-c. 1600)\n\nCoptic was the last evolution of the Egyptian language before it dies and replaced by Arabic

I think you have that backwards.  There are no physically existant tablets of emerald (or jasper, or tanzanite garnet) which were engraved with the writings.  There are no Atlanteans, much less Atlanteans who are responsible for its writing.  And there probably never was a Hermes Trismegistus either.  The Emerald Tablets of Hermes is an ordinary book that was written in the 12th century in Latin.  And while it is possibly a redaction of an older 9th century Arabic text, both the 12th and 9th centuries are decidedly post-biblical. It was quite common at that time for authors of mystical texts to attribute their writings to someone older and long deceased but reknown, in order to lend their work more credit.  It was also common for some of them to invent fantastic tales that anyone with a shred of common sense would realize were complete and utter tosh.

A woman in the Bible had one for 12 years.  In all seriousness, you would have to give much more information for anyone to answer this question...

Yes.  Egytian hyroglyphics show dinosars.  Other cave drawings show dinosaurs.  Europe and Asia both have a lot of mythology about dragons.  Leviation, mentioned in Job 40, breathed fire.
