Can the High Costs of Space Exploration Be Justified?

Firstly, I would like to reinforce the fact that the benefits perceived from space exploration are highly overrated. These "hypes" are created by space agencies, who try to justify the costs of space exploration in the eyes of the public.
As we all know, numerous resources are devoted to space exploration.
Space agencies claim that they can alleviate the sufferings of millions of individuals around the world by finding cures to fatal diseases such as HIV, AIDS and cancer. This is well and good, but unfortunately it is only a hope. There is no fact, there is no definitive to say that this will work. We are equally likely to find a solution to these problems on earth as we are in outer space. So why spend billions when we can do with millions?
Ladies and gentlemen, we are not denying that there are benefits from space exploration. We only claim that the costs involved do not match the benefits received, even closely.
