Abraham existed so long ago that I suspect this probability is significantly large, maybe > .05

Can somebody do the maths?

I read a study years ago that says 90% of ethnic french people are descendents of emperor Charlemagne, even though it's been "only" 1200 years.
Abraham being born thousands of yearw ago, his genes must have spread all around the mediterranean and beyond

these are not real jews
the jews are evil
we are the real jews

Adam and eve were aryans. when noah and the aryans arrived after the flood they brought with them the exact same shit that noah did.
The book of genesis is the history of the aryans told from the aryan hebrew perspective

the aryan hebrews went into europe as the cimmerians and scythians and became the celts and saxons.
so to answer OP's question, all white people are descended from jacob (israel) thus descendants of abraham. The answer is 100%
