As to becoming a movie, I have no doubt, and it will happen faster than you can imagine. With the TV series SG-1 in the body of the genre, and the soon to be released or released prequel to Aliens, this story you've woven needs to be told. Humankind may well be on the verge of open contact with extra terrestrials, so we can use all the different perspectives we can assimilate.
As has been the nature of humankind, we use our fictional (read imaginations) realities to prepare our minds for practical realities. You will be a major contributor to our mental file data, judging by your mastery of the craft. Keep writing, we need more and more.
Thank you for your kind words.
