If we look closely into the Sanskrit alphabet, we will notice that it is actually a form of caligraphy, a reproduction or variation of another alphabet. This is why we see vertical lines and upper horizontal lines to serve as aiding scale in keeping the proportion inside an imaginary frame. Also being written from left to right

, it seems to mirror the existing right to left typo of languages like Avestan, Hebrew and Arabic.

Back in time to more than 1500 BC, Avestan was the liturgical language of Zoroastrianism.

Sanskrit means "sanctified, refined", fact that makes me think that the writing tells the story of an ancient imperial expansion into a foreign land by transmission of language and sacred text. The language itself has not evolved (besides various dialects pertaining to different regions of india), nonetheless, different forms adapted by Nepali, Thai and Tibetan people have developed. As far as I see,Hebrew language is also part of this liguistic genealogy, not the phoenician one.
