I remember reading it in a book with following claims, but i haven't verified any of the sources
1. Brahmi is found throughout the sub-continent and in Ceylon.
2. Brahmi has been traced back to the Phoenician type of writing represented by the inscription in which Mesha, king of Moab (c. 850, BC), records his successful revolt against the kingdom of Israel. It was probably brought into India through Mesopotamia, as a result of the early commerce by sea between Babylon and the ports of Western India. It is the parent of all the modern Indian alphabets.

1. I don't see how Ceylon can be the origin. There is no evidence to back this.
2. How can Brahmi numerals have come into India around 850 BC when Sanskrit already existed during that time period. Again, these claims make no sense. Brahmi scripture is considered older than Sanskrit. How can it be introduced after Sanskrit was already popular? The Vedic scriptures (written in Sanskrit) date back to 1500 BC. Why is it so hard to not realise that maybe it was Mesopotamians who accepted the Brahmi numerals and not the other way round?
