Assuming that they can fold space and time at will, is a massive assumption. There is probably no more than a 1 in a trillion chance that the enemy aliens who come to attack us have that specific tech. There is even less of a chance that they can employ it at will on whim. It might take hours to power up a device like that, or it might require more fuel than they can squander if they ever want to go back home.
They are coming from another star. We measure elements, molecules and compounds in other star atmospheres. So what qualifies as a "long distance?"
You don't know that.
Really? Why not? We have already detected what appears to be the beginnings of primordial life on planets around other stars.
Technology and intelligence are a relative thing.
Really? Why not? You think they don't know what radar is?
What radar detects ships coming in from other planets at faster than light?
Radar follows a progression of natural technological evolution following the natural laws of the physical universe.
8 billion people all trying to survive living in bunkers and sewers. What could go wrong?
Why would you expect this alien species to have the same "moments of brilliance" that all of humanities best inventors have achieved? There is virtually no chance that they invented Radar tech. The aliens invented some other detection system, and its probably much better than ours, but they wont have anti radar tech. No way. The odds of that are astronomical.They are coming from another star. We measure elements, molecules and compounds in other star atmospheres. So what qualifies as a "long distance?"

Well, I do concede that they could dodge the missiles by just going back home, but it would ruin their entire invasion plan. I doubt they can do that trick at will. It takes time and preparation, maybe even super rare elements that have to be harvested on other planets.
Why? Why are you assuming that radar is something that every intelligent lifeform will invent? Thats totally unrealistic. If you throw a random intelligent advanced alien species at us, there is almost zero chance that they also came up with that super oddball technology. They invented something else.
Thats an absurd claim. The existence of radio waves in space, doesnt mean that every alien world will "naturally" invent radar tech. Technology isnt discovered naturally. It requires a single individual to come up with the idea, before anyone else has ever even thought of the idea. Moments like that are vanishingly rare.
If that is true, we are doomed.
Not really. How many alien planets even have the tech for long travel in space? Out of those, how many are going to discover Earth? Out of those, how many are going to be instantly hostile?
Can you provide an example of a primitive civilization that survived the encounter with a more technologically advanced one? Hostile or not, just meeting an alien race will radically change us forever. That is the idea behind Star Trek's Prime Directive and Fermi's Paradox tells me the aliens are already here.
Doesn't even need to be harmful. There is a term for this: Cargo cult
I remember one famous astronomer pointed out, that the concept of "Star Wars" was unlikely. Since far apart civilizations would likely never be on the same rung of the technological ladder. So the two sides would likely be so mis-matched.
