Do you think spending much money on space explorations and studies such as the search for life in other planet

Space exploration is just that... exploration. To know nothing higher than ourselves and our petty problems is not only a sad way to live, but it is against our nature. We are justified in spending the money because knowledge of the universe enriches our lives, not because it is going to turn a profit. We need to learn as much as we need entertainment or vacations... and no one questions the validity of those things.
