When one major culture adopts the tongue of another, they usually do so because the adopted language has a specific advantage, most always the advantage being of the language having a written script(the Thai script is a stylised Indian Tamil script). But Indian languages, given the similarites with ancient Greek, have a totally different script compared to the European languages.

So this theory that Indians borrowed only language, of the spoken form, and not the script, has some holes to patch.
