In order to establish something to be inhabited, you need some kind of evidence, not just presumption. In addition, there are many islands that are not large enough to sustain any kind of lived-in habitation -or may be barren or lack fresh water. Stopping over to repair a canoe is not inhabiting some place. At the minimum an inhabited island would need enough resources to sustain a family, more likely an extended family and perhaps a settlement to be long-term inhabitable.
