Until we have just one datapoint from another civilization or planet (just one!) every single statement surrounding Fermi paradox stuff can't be proven, for example:

- Life has to go through "hard steps" to get to civilization

- (I really hate this one at a personal level for multiple reasons) assuming alien civilizations will use Dyson spheres

- There exists some sort of 'great filter' that prevents civilizations from expanding

For each of these, we have absolutely no data to compare to in order to support or refute these statesments.
