it's because the jews are clutching trying to claim it has to do with them. the a comes from the sideways phoenician symbol, not the aramaic derived aleph version. semitic languages are abjad's too (means vowels aren't written), and the phoenician symbol didn't make an 'a' sound. it was a symbol appropriated for greek alphabet as 'a' vowel sound since the original phonecian sound wasn't needed for greek.
