Aliens finally land on earth - just like in the movies. They are not friendly. Would Earth win a war with them?
Let’s suppose, for the sake of argument, that unfriendly aliens landed on earth. (Roughly paralleling the plots of The Invaders, War of the Worlds, Independence Day, Mars Attacks, and The Day the Earth Stood Still).
In some of the movies, humans win (ID, TDTESS, WOTW) and mankind survives. In others, well, not so good.
But those are movies.
What do you see as the real outcome of unfriendly aliens landing on Earth?
My view: mankind is destroyed or enslaved.
First, we on Earth never act as one people. We would argue for months on political issues regarding whether to fight back in the first place. And there would be some nations and groups that would ‘sell us out’ for personal survival. Throw in some of the apocalyptic religious groups who would be praying for earth’s demise, and it is a recipe for disaster.
But even worse, if an alien civilization has the technology to research us, travel here, and land here with a conquest plan, then they by definition would have the technology to annihilate us in a dozen different ways. Human thought (along with current disdain for scientific research) simply has hobbled us from making the scientific leaps required to build nebula-level defensive weapons.
My view is that once nasty aliens appear, we’re doomed.
