There is the hidden assumption in these calculations that interstellar migration is impossible. This is not a scientific assumption but dogma. There are many conceivable ways that such migrations could take place without resorting to assumptions of Star Trekian warp drives, but at sub-light speeds. E.g., assume machine intelligence and length of travel doesn't really matter. Time to nearest star at a very modest 1% light speed is then less than 500 years. NASA propulsion experts for years have been thinking in terms of 10% light speed for a probe. Once migration enters the calculation, the numbers of possible civilizations could soar from the thousands to the billions and nearest civilizations could be next door instead of thousands of light years away. Ironically Fermi in his famous paradox assumed that very advanced civilizations would have interstellar travel and they should be all over the place by now if ET civilizations existed. So why aren't they here (the "paradox")? Of course, many of us here turn that on its head saying they are here and the evidence is the UFO phenomenon that many scientists refuse to even look at. If they are here, then there is no paradox, just a refusal by some to look objectively at the evidence right under their noses. David Rudiak Listen to 'Strange Days...
