sanskrit was the first alphabet

[Siren]

Atlantis is known as a high civilisation. I would have thought they would have had literacy, but perhaps it was symbol based (a la Chinese) rather than alphabet based.

Is it really too hard to fathom that words and books and written texts did not properly exist prior to the times of Sumeria? I don't mean to imply there weren't any graven symbols, images, or glyphs being used, but these were symbolic, conceptual, merely evocative (thus reverberating into the deeper chambers of mind). "Symbols of power," if you will.
Plus, communication need not be textual when you understand the truer significance and use of sound.

Just think about it, why would there be any need to keep written records when you could perhaps access a more... let's say, collective reservoir of planetary memory?

The truer, purer, infallible "history" will always be embedded in the mind/memory. Not in a book, or a tablet, or a ziggurat's wall.
