That's the most ignorant thing I've seen said in a very long time. We'd still be living in caves, and bashing rocks together, if everyone had your mentality. You wouldn't be using advanced micro-technology were it not for space exploration.

Also, a great deal of our tech came from, and continues to comes from, space exploration and the technological advances required. We ignore space at our peril.
