Bluefish Caves, with its date of approximately 24,000 calibrated years BP, does not establish when the first person entered the Americas.

It establishes that there is direct evidence of human activity in eastern Beringia at approximately 24,000 years ago.

People may have been in eastern Beringia earlier than that — the absence of evidence from earlier periods is not evidence of absence.

People may have been in other parts of Beringia or in the Americas proper at comparable or earlier dates — the evidence from Bluefish Caves is specific to the Bluefish Caves location and does not preclude contemporaneous or earlier activity elsewhere.

What Bluefish Caves does establish is the presence of an archaeologically documented human activity — carcass butchery using stone tools — at a specific location and at a specific time.
