I truly do not know what to make of this. I don't know about tones or sounds. I'm talking ...I know nothing!....about this kind of stuff. Since I didn't hear any "words" that I could understand and no one is saying that it is a language that is common to any of us then i am unsure why they are said to be "speech patterns" but I do believe NASA if they are saying that they do seem to be some kind of speech patterns. Also I was unsure if the real pretty music they were playing was part of the radio transmit or if it was music that they added to the video. ???
However I do trust Ghost1 and if he says that this is incredible then I believe him also.
