The cited passage

What current science says

If all 8 billion humans today descended from just 8 people a few thousand years ago, our genetic diversity would be vanishingly small — far less than what we actually observe. Human populations carry thousands of distinct HLA immune system alleles alone, which could not have arisen from 8 people in a few thousand years (mutation rates are far too slow). Population genetics consistently shows the human species maintained an effective breeding population of at least 10,000 individuals throughout our history. Additionally, isolated populations like Aboriginal Australians show continuous genetic lineages going back 50,000+ years with no flood bottleneck. The genetics simply don't fit an 8-person restart.

What the text says

This comes from 1 Peter 3:20, which states 'eight souls were saved by water' — asserting that a global flood killed every human on Earth except one family of eight, making all subsequent humanity descendants of this single-family bottleneck.
