If one just studies the extremophile lifeforms that exist on earth now we can see the tremendous variety there is to life. Creatures exist in boiling water, the arctic, heavy water pressure, low oxygen, no oxygen, sulphur synthesis. You can't look at humans and assume that we are the only form life, intelligent life, can take.
The "habitable zones" of stars are not so small that it is impossible to find planets in orbit in them. Yes, there are necessary and helpful factors, but when you cross that with the trillions of stars out there that number of planets is still a huge number.
Just because they haven't landed on the lawn of the white house, yet, doesn't mean that they won't. If travel by wormhole is the way they get around Einstein then creating a wormhole, stable enough to use would require a massive amount of energy. They really would need to want to go where they are going.
Our earliest radio broadcasts are still pretty close to us, relatively speaking. Probably once our broadcasts hit them, and if they are listening, then maybe they'll visit.
Another thing to consider is that perhaps their radio signals passed us when we were still zug zugging Lana. They could be broadcasting via a technology we cant receive yet. If they're broadcasting FTL now then there is no way we can pick that up. If someone was broadcasting by microwave transmitter back when we were first hooking telegraph lines, we couldn't listen to that microwave transmission.
There's a ton of factors and thousand shades of gray.
