Seriously, if a alien horde were to show up knocking on our doors, then it would be obvious they would be vastly more technologically advanced than us, it would be like the Mongol throwing rocks and arrows at a challenger tank, just because nuclear weapons are the most destructive weapons we know off doesn't mean they are the be all end all and nothing can survive their use.
Think about it. If an alien species has interstellar travel, then they also know that energy is precious and that once you leave home, generally what you have is what you got. Why would these intelligent, space-faring aliens waste that precious energy on resource-expensive weapons when firing a bullet or missile as we do can get most jobs done just as easy? There's more to space travel and space combat than simply having fuel to get from point A to point B in a timely manner and having the biggest gun.

Sleepy, what are you on about? Last I checked, we've already developed all the WMDs: we have nukes, we have biological agents, and we have chemicals. Unless someone has an antimatter bomb or can somehow create a singularity to destroy the earth, I don't really see what else we can make.
