As in all things there is no paradox, just an open question, no paradoxes exist.
One can falsify the fermi question. It is falsifiable.We have failed to falsify it.
One cannot disprove, only fail to provide a proof of possibility in an axiomatic system like mathematics, and reality is a theoretic system, not axiomatic.
At present it is falsifiable, un-falsified, and undecidable, and therefore all we can say is that “we don’t know yet”.
The most obvious reasons are:
1 – Technological (EMR is a primitive technology)
2 – Differences are such that we would be of no trading (cooperative) value; interfering would only create a competitor; and it is too early for a colonization effort to have reached us given the recent development of EMR broadcasting.
3 – Time and distance window of opportunity
4 – We are in a calm location between arms, in a calm (dying) galaxy, and have had long enough period of growth to ‘bake’ in necessary conditions
5 – I am concerned that the spinning liquid iron core of our planet that creates its defensive field is rarer than we imagine, and as such it is much harder for life to have time to bake. taken to the extreme, the question may be, now many planets can survive four to five billion years, in a safe rural area of a galaxy, in the habitable (water) zone, while maintaining a spinning liquid iron core?
