Supposing there was a natural calamity in which all countries and peoples were wiped out BUT Nigeria. Would the surviving Nigerians be capable of re-creating the state of development we currently enjoy in the 21st century? How long might it take for Nigerians to do this - 100 years, 500 years, 1000 years?

In fact, as far-fetched as this might seem, it is not an idle question. In view of the fact that 99% of all species that have ever lived are now extinct, it is reasonable to assume that humans might one day suffer the same fate. Further, humankind is at the mercy of natural forces about which we have only rudimentary technology to defend ourselves.
