Unusual story this right now. Found on the UK paper, Daily Mail, some foreign news sites and bloggers commenting on it. Unsure if it is real or not. Marth Othma alreary works within the UN as head of the UN's Office for Outer Space Affairs (Unoosa), and a recent conference speech she gave explained how we need such an ambassador sooner than later. No source has said exactly who expects her to become said ambassador. Here is where the story breaks down a bit and may be some fanciful 'out there' writing by the Daily Mail desk. But given the UN's power around the world, if aliens did land in many countries, would those countries allow the UN to lead first contact situations?
