If aliens have the ability to travel far enough to get to Earth from anywhere else, we better hope they are friendly. That kind of technology will probably include some pretty awesome death rays.

Hopefully interstellar travel is pretty simple like in Harry Turtledove's The Road Not Taken. Otherwise we would be about like the Aztecs and Incas standing up to the Spanish.

Road not Taken is one of my all time favorite stories simply because it is such an unusual concept.

I’ll have to read that. I’ve considered the possibility that we’re missing certain technologies simply because we think inside a certain box. That’s why I think its important to at least consider some pretty wild ideas.
