How did Noah relocate the penguins back to Antarctica?

And the kangaroos to Australia? And the lemurs to Madagascar? And the alligators to North America? And the impala to Africa? And the polar bears to Alaska? And the tigers to India? And the caymans to South America? And tyrannasaurus rex wherever the hell he lived?,all before ships or aircraft were invented, and remembering, Noah was around 600 years old?
