Since no one answered your question really, except maybe the video I didn't watch, I'll explain a bit.
European languages all use basically the same alphabet - just as they all share a common ancestor (with the exception of Finnish, Estonian, Hungarian and Basque). This was derived from the Phoenician writing system, which was in turn derived from Egyptian hieroglyphics, whose origins are lost to time.
Indeed, aside from the Chinese character writing system, and the Korean hangul writing system, fairly well all writing systems currently in use in the world are related to the one used by European language speakers. Two great unknown, is if devanagari, the system used by many Sanskrit-derived languages, is related was independently created; and if the Georgian wiring systems are similarly related or independent.
