GeekSpeak – the Fermi paradox: where are the aliens?

“Where is everybody?” – Enrico Fermi.
The Drake equation suggests that there are many technologically advanced civilisation in our galaxy.  But if they do exist, where are they?  Why have they not come to Earth?  Why do we see no sign of them?  No radio messages, no von Neumann probes, so sign of Dyson spheres.

There is no reason to think there is anything unusual about Earth or about our solar system.  Exoplanets are commonplace.  Life began on Earth as soon as it could begin so it must surely have occurred on many other planets.  Plenty of them must be much older than Earth and must have produced intelligent species that want to explore the galaxy, just as we want to.  Where are they?

Are we looking in the wrong place or in the wrong way?  Do advanced civilisation always destroy themselves before going into space?  Are we the very first?  Are the others avoiding us for some reason?

Bring your telescopes to GeekSpeak and give us your answer to the paradox.
