What a load of crap (Score 1)

"The Fermi paradox says that if extraterrestrial civilizations exist, at least one of them should have colonized the entire galaxy by now"

Why can't there be loads of civilizations in similar states to our own, why *MUST* they be so advance that they would be capable of colonising the entire galaxy by now. Even if a civilization was more advance than us who is to say that they are capable of interstella travel. Dosn't this assume some kind of startrek technology is possible? What if its not. So a civilization builds an ark or two to escape a dieing solarsystem and moves to another, thats not talking over the entire galaxy is it?

If life is anything like our own, any sufficiently advanced civilization will have had plenty of chances to nuke themseves before they even got past their local moon.

There are so many things wrong with that logic!
