The first humans to leave Africa would likely have used boats to follow the southern coast of Asia, and crossed the Bab al-Mandab Strait (today's Djibouti to Yemen) and the Strait of Hormuz (today's Oman to Iran) to accelerate the process. The most difficult crossing would have been the Timor Sea to reach Australia; even at the height of the last ice age, it was several hundreds of kilometres across. Surely the latter would have been far more daunting from a navigational perspective than following the Aleutian island chain?
Also, boats and travels would imply a sea food based diet and a maritime society, that is more advanced than the Smithsonian's hunters and gatherers, that are living in caves and getting tooth decay.

The idea that ancient peoples did not know how to build boats and travel even just along coastlines is simply preposterous.
