If ET's have mastered nanotech, their devices would be microscopic or pebble sized (depending on their purposes). And if they've mastered
bioengineering, they'd have living organisms as some of their machinery. Combine the 2 and they may arrive as camouflaged, cyborg "insects" lol. No
one that I know of is dissecting mosquitoes to see if there are microscopic alien tech inside controlling them. And for the scientists that have
looked, they may have called that technology "viruses" (or even confused it for a natural variation of life).
And you're right that they may not use craft at all. I just imagined that the scenarios in the OP take so long to reach Earth because the ET's are
simply checking each planet and its moons along the way. And doing other up close studies throughout the solar system, like studying and getting
samples from a lot of objects in the Kuiper belt (just an example, it doesn't have to be that specifically). Our amateur astronomer in the OP just so
happened to spot them while they were on step 1,260,000 of a 2 millon step campaign. And visiting Earth just happens to be step 1,365,247.
If they were capable of teleportation, I think the best use would be for things like sending back samples and retrieving packages (like food and
maintenance supplies). They may even have limits to their teleportation technology, such as only being able to send objects a certain distance or
having to build "receiving and sending stations" along the way. And depending on their internal laws/policies, they may have limits for how much they
can send at once because of environmental or alien workers' rights issues, meaning they'd have a backlog of samples to send back. These would also
explain their relatively slow advance through our solar system.
