There's no reason to put humans out there. There are no aliens. There's nothing out there for us. That's why we send probes. Cheap probes. Unmanned probes. If we happen to discover something amazing that would be interesting or beneficial to walk up next to at incredible risk and expense, then perhaps we would do a manned mission. But its far far too limiting to send people in every direction to do the exploratory probing. You can explore a 1000x more volume of space with robots than you can with manned missions. We can't even see anything worth sending humans to with telescopes. We don't make manned space probes for roughly the same reason we don't make manned torpedos. There's no point to the expense and risk. Use the right tool for the right job and put down the science fiction.
