List two ideas of how the first people came to Papua new Guinea?

1. One theory suggests that the first people arrived in Papua New Guinea by sea, using canoes or other watercraft to navigate the waters of the Pacific Ocean. These early seafarers may have come from nearby islands or even as far away as Southeast Asia.

2. Another possibility is that the first people to inhabit Papua New Guinea arrived on foot, crossing land bridges or narrow stretches of water that connected the island to neighboring landmasses during periods of lower sea levels. This would have required a significant amount of time and effort, but could help explain the presence of early human populations in the region.

1. Island Hopping: Some anthropologists believe that the first people arrived in Papua New Guinea by island hopping from Southeast Asia across the islands of Wallacea, a chain of islands between Indonesia and Australia.

2. Overland Migration: Another theory suggests that the first people came to Papua New Guinea via an overland migration from Australia through the Sahul land bridge, a landmass that connected Australia and Papua New Guinea during the ice ages.
