I have a problem with the idea of "The First Americans"

[Not rock pile related]

They talk about "First Americans" as if it was obvious that there was a first time Homo Sapiens stepped onto land of the Americas. It seems to be a persistently pointless discussion that seems to lack the kind of verifiability that is expected of scientific hypotheses. 

For example: it might have been lots of people "stepping" onto America, in different spots, at essentially the same time and, it may not have been Homo Sapiens. 

Update: I was thinking it is a bit like the chicken and the egg: it suggests that there was a "first chicken". Kind of a pointless way to think about the evolution of birds, eggs, and the modern chicken.
