You have a time-line problem here. Pangaea was some 500 million years ago, noah was about 7000 years ago. His culture was dravidian, remnants of which still live on in india. Gondwanaland(the southern supercontinent) developed marsupials(kangaroos)and fossil marsupials are found in south america. The BIG dinosaurs went extinct with the Yucatan meteorite/nuclear winter event of 65 million years ago, thus the rise of mammals. But when pangaea split they developed in different directions. There NEVER was marsupials on the eurasian continent, but noah was clearly a pakistani living in the delta region of the Indus River. Do some research...
