There’s no archaeological record to speak of! We can talk about what, logically, was likely to have happened, but there isn’t evidence and we’re not likely to ever find evidence one way or the other.

The entire complaint here has to do with overconfidence in these sorts of statements, all to prioritize a harmful narrative with a motte and bailey where you excuse a harmful reductive narrative, will only defend that some people at some time traversed Beringia on foot, which was never disputed.
