This is an important issue because if we have been visited by alien lifeforms, they likely have better technology and a greater insight into how our physical universe works. This type of information should be open to the public. This effects all inhabitants of earth because as we grow more divided and hostile towards one another, this would give us something greater to focus our efforts on. Ideally we could begin a global effort to colonize the galaxy. This would create numerous jobs, drastically improve our current technologies both in space and at home, promote international peace, and help advance the human race as a whole.
