I beg to differ...We clearly have the edge in battle and weapons intelligence. Just look at all the movies. All we need is an alien fuel rod, Will Smith, and the ability to shut down there communications tower. It's the same formula every single time.
Some even have weaknesses to water (ala the movie Signs) our planet is 70% water. Melt the ice caps (water world) = 100% protection.
Suck it aliens
