A rough idea of the scale involved:
The hypothetical alien mapping mission of this galaxy uses ships that can travel instantaneously between solar systems. No warp factor 9.9 stuff here, we're talking instant travel over any distance.
So they only use time investigating each solar system.
They`re only doing a really superficial survey, so extremely superficial that they only spend one day in each solar system. Just one day to survey an entire solar system.
It would still take 273,792,574 ship-years. Even with a fleet of 1000 ships all doing only this survey mission every single day and with perfect efficiency, the survey would take almost 274000 years.
So how likely would it be that they happened to be around here so recently that our technology was advanced enough to detect on a brief survey of our solar system?

I've always thought if there was something so advanced out there, they would have found us and done... something
Left quietly after putting up a warning sign for others :)
They`d have to be incredibly advanced to find us, except by chance. Even if they were advanced enough for interstellar travel to be routine for them, how would they find us otherwise? There`s absolutely no sign of us more than a tiny distance out from Earth and even that sign is extremely faint unless you`re more or less here already. Even if they have a fleet of ships exploring, it would take eons to cover everywhere. Even if they had passed by Earth on their grand mapping mission, chances are it would have happened long before any human technology they could detect existed. A quick scan on the way past...nothing interesting there, on to the next planet.

There's really not much basis for that statement, not to be argumentative, but we don`t know what is out there or if it`s more advanced than we are ... so "marvels" may not be the best word, but in our own right we`re definitely advanced
Same answer as before, really. It doesn`t matter if there are more advanced people elsewhere, or even if they come here. We`re still marvels. The pinnacle of billions of years of change. The ape that asks everything and finds answers.
