IF there were an alien invasion, you would die.

I should first say that I have no degrees beyond a high school diploma. I have no training, no associations, and no experience, that would make me specially qualified to say anything. I'm just writing how I feel and from my own imagination.

I'm watching a special on the hypothetical sequence of events following an alien military invasion of Earth. There seems to be quite a few leaps in logic being made by the folks behind this special. They seem to be modeling their invasion after any number of movies. Many of which were incredibly illogical and flawed to begin with. While I applaud the effort being made here, and they are indeed making some interesting points about the human panic and self-destruction that would occur, I can't look over some basic flaws in the scenario being presented.

My problem begins and ends with the initial invasion; any being able to travel across the universe would never initiate an invasion within the atmosphere, and especially not on the ground. If a military invasion were to occur, the invaders would remain in space. First they may or may not tap the satellite systems of the world and monitor all communications and broadcasts to establish a base understanding of the who, what, and where. If they did monitor broadcasts they would continue until the invasion has finished. Below I'll list three, of countless, possible attack scenario's;

Attack 1; Infection; Probes filled with an agent, either biological or nanotechnology, specifically designed and created to destroy humans would be deployed in the atmosphere. There it would spread around the world infecting everyone. The second, and slower variation, would be an agent spread through physical contact.

Attack 2; Radiation bombardment; From their ships, or deployed probes, the invaders send down massive amounts of radiation. Essentially microwaving us where we stand. It would be comparable to countless nuclear weapons being detonated.

Attack 3; Terraforming Event; The invaders begin a terraforming process which physically alters the planet into an environment we simply cannot survive in.

The fact is if hostile alien invaders were to arrive the one thing they wouldn't do is engage in any sort of direct assault. They would remain out of reach of any kind of resistance, and would simply destroy whatever they wished. If, in this scenario aliens invaded, the only chance humans would have would be if we were on a comparable level in our technology. If we have ships of our own, shields of our own, abilities of our own, than we would be able to stand at some sort of reasonable level. As it is, right now, we simply can't.

Survival is for the intelligent.
