I grew up near Kennedy Space Center, and actually worked out at NASA during my last two years of High School with the
US FIRST Robotics competition. Those NASA guys are doing some great and important stuff so I'm among the first to defend this country's space program. However, there is a side of space exploration that I truly feel is such a monumental waste of time, money and just pure brain power, and that is the search for aliens.
I'm not saying this because I believe that there aren't other life forms out there (for the record: I believe there aren't), I simply think that if there are they are either not worth all the effort we put into finding them, they don't want to be found or they are perfectly capable of finding us without our help.
Let's first explore the ulterior to these three options which is of course that there is something (dare I say someone) out there worth finding. The most common and appealing reasoning for seeking life on other planets is that this life may be far more technologically advanced than ourselves. If this is the case, they will have a lot easier time finding us than we would ever have finding them - so just let them!

If they are not technologically capable enough to finding us, why bother looking for them? If they are technologically advanced but don't want us to find them, we probably should not want to bother them either!
There's always the argument, "Well, what if they're not technologically advanced but can provide something else wonderful for us humans... Like their piss can cure cancer or something." That could always be the case, but perhaps there's an unknown organism at the bottom of the ocean whose piss can cure cancer, and we know far less about that environment than our immediate universe. Furthermore, wouldn't it make more sense to spend our time, money and brains actually
looking for the cures to our problems than looking around for someone who might not even be worth finding if they even exist at all?
It's ridiculous some of the things we blow millions on trying to find these alien forms that we have no reason to think exist (other than the occasional hoax or nut-job that says they saw an alien.) Take for example
SETI. Their whole thing is sending out a message into space. Since the electromagnetic spectrum is far too large to send out this message on every frequency someone out there might pick up, SETI just sends out the message at 1420 MHz - 1660 MHz (mostly just at 1420 MHz, really.) The EMS goes from 0Hz to infinity EHz! That's... (twelve times infinity... carry the one...) an
indefinite spectrum that our alien friends could be monitoring. Silly.
Ok, I've wasted enough breath on this. It's going to be funny when this
Stan Romanek video turns out being real. I for one would welcome our new alien overlords.
