What is the leading theory about how early humans arrived on the American continent was the answer they walked from Africa to South America when those two continents were part of the same landmass or did they walk to Asia to North America over a strip of land that has since been covered by the ocean or did they sail in large ships through AustraliaI’m or did they canoe from Antarctica to South America when the climate became too harsh

The leading theory about how early humans arrived on the American continent is that they migrated from Asia to North America over a land bridge known as Beringia. This land bridge existed during the last Ice Age when sea levels were lower, exposing a connection between northeastern Asia (what is now Siberia) and northwestern North America (what is now Alaska). This migration likely occurred around 15,000 to 20,000 years ago, as humans began to populate the Americas.

The other options you've mentioned—such as walking from Africa to South America, sailing from Australia, or canoing from Antarctica—are not supported by the current evidence and are not considered likely pathways for the initial human migrations into the Americas. The Bering Land Bridge theory remains the most widely accepted explanation among archaeologists and anthropologists.
