The chances are around 260k to 1. Factoring Eve’s lack of a second sex chromosome, (unless she has swyer syndrome) the equation would be 1/((22²+1)(23²))≈0.00039%

Seeing how we’re talking about religion and first man, I don’t think we’re limited by probability here.

BTW so there are 30k people with identical chromosomes??

  As you mentioned it depends on chromosomal differences, I just provided the probability of it actually happening.
  
  And, yes. Barring any mutations or trait selectivity, if we all came from the same individual, there would be about 30k identical people of the 8.1b population.
