The earth was much warmer then, so everywhere had less ocean between them than today. It does appear that the AA got to South America well before the American Indians came over from Japan. Maybe as early as 50K years ago.
Im not saying we did. But land bridges work both ways. Some people are questioning the accepted Africa theory and Australia has been mentioned.

Ghost lineages. The Neanderthals live on- within us!More cousins. These guys were around a long time, and split the scene not too long ago.
The scientists estimated this ghost lineage diverged from the ancestors of Neanderthals and modern humans up to 1.02 million years ago and interbred with the ancestors of modern West Africans from 124,000 years ago up to the present day. "One limitation of our study is that we have mainly sampled present-day West African populations," Sankararaman said. They don't know yet how far the ghost lineage spread across Africa, he said.
Scientists Find a Mysterious 'Ghost Lineage' In the DNA of West Africans
Researchers find evidence that a group of still-unknown humans interbred with our ancestors.
They do in lots of us in tiny amounts. But this is genetic evidence of a group of Neanderthal/modern human hybrids {for lack of a better word} in west Africa as few as 124,000 years ago. It's only showing up in west Africans so far, but that is about the only place they have been looking for it. Now they just need to find the bones to go with it.
