Interesting theory but it doesn't follow the theorem, evidence of absence is evidence of absence. Going by language Hebrew is West Semitic, putting the ancestral culture of both Hebrews and Arabs solidly in Eurasia when they lost mutual intelligibility.

If you're talking genetics nothing is debatable, I agree that a prehistoric Inuit man once journeyed back out of Alaska and is an ancestor to everyone alive by virtue of his genes having so long to spread around the earth.
