All good points, but do we need to consider the threat from lovesick teenage vampires as well?
Just putting that out there.
what if the aliens WERE zombies?
what if the aliens WERE zombies?
now thats just silly
The concept of intelligent alien life first seeking to spread across the cosmos and, having done that, finding its way to a tiny, remote outcropping of the universe as randomly situated as earth defies probability. Not to say there isn't intelligent life out there, but it would take a pretty wild coincidence for them to locate and travel to this planet. We can assume that they would encounteer our radio signals that are sent out, but there is no way to know if such beings would even utilize radio signals. When you think about it, there is almost certainly life outside of our sphere of observation, and most of it is bacteria or other types of microorganisms. But having a situation where more complex intellgent life devleops and then focuses their efforts on the development of technology necessary to scan for other life and travel to find it over huge, almost unthinkable distances -- that's probably not all that likely. So chances are, we're not going to be getting too many visitors -- at least, that is, before the time comes when a super virus creates zombies that come to eat our brains (and move faster than they are depicted on tv.)
So between zombies and aliens, probability dictates that it's going to be zombies.
But all of that is moot anyway. What's going to kill us all first are the sharknados. I mean, they're f*cking sharks flying through the air in random patterns caused by destructive weather systems. How do you even begin to fight a foe like that?
Given that there are billions of galaxies (probably more), with billions of stars in each one, the statistical probability of alien life is pretty good. For them to traverse great distances requires technology that allows travel faster than the speed of life, such as bending space to bring 2 distant points closer together, artificial worm holes, warp bubbles, etc. There are sources of energy in the universe great enough to make these possible, and just because they are beyond our technological and intellectual capacity, does not mean someone or something else out there has not developed it. Then there is this notion that life only exists in the physical universe that our senses allow us to perceive, but that is a whole other discussion. If a race were advanced enough to harness these energy sources and technologies, what makes you think that they would be interested in us? We are not the center of the universe. They may be as interested in us as we are in an ant colony, and do you go around initiating first contact with every ant colony you come across?
Zombies, and this will be my theme song as I bust caps into their coolers:

. still going with zombies ...
I originally voted aliens but 1speed is talking some bad ass science up in here. I'm thinking zombies.
