... He's merely just speculating Phlo', largely just to incorporate a number of the objections you raised earlier regarding finding it hard to accommodate the notion of a technologically advanced alien civilisation evolving from subterranean life underground on a planet in our own solar system - not so much saying that he believes particularly that indeed, this notion of an advanced civilisation making a slow trip across the cosmos particularly happens to be the case, but is pointing out that were a civilisation capable of developing the kind of technology that could conceivably sustain a population indefinitely over the course of a journey lasting possibly generations successfully enough to begin with - arriving here and colonising one of the other planets in our system would merely be an application of that exact same level of technology....
We generally tend to assume a world such as our own suitable for habitation universally - in terms of atmospheric composition and density, temperature etc, perhaps as far as life remains concerned this may yet prove to be the case - there are undoubtedly always going to be a degree of variable in all these sorts of criteria - but the one that no one, or thing for that mater, is ever going to get around artificially is that of a planets gravity.
On board a vessel of some description, gravitational conditions can be simulated relatively easily and indefinitely - but if looking to set up shop somewhere else, in order to be able to look in the first place, technologies involving long term, indefinite life support would undoubtedly have to be refined to an art form - if, however, you're looking for some planetary body on which to live indefinitely after having undergone such and undertaking, it's mass pretty much has to be consummate to that which one's own home world exerts, gravitationally speaking, otherwise life becomes somewhat less than comfortable if indeed gravitational force happens to be too high...
Basically, he's merely speculating about what we would do were we inclined to be slightly more inquisitive about the universe and asking is it so unreasonable to assume the same of others.
