We haven't colonized the moon either
Pretty hard to justify. And what exactly constitutes "colonization"? IMO colonization is possible when anyone can save up their money for 10 years at most and make the journey. Clearly lunar colonization isn't yet possible, even if we can send probes and a few landers. But with interstellar travel, we are still in the 50,000+ years transit time. Not good enough even for a probe.
