Speaking generally, the only reason a more nuanced explanation exists is to show that the Church does in fact have something to say about science and that it does in fact matter to the secular world. However, “divine intervention” is not a scientific concept and will be immediately rejected ny nontheists as part of any scientific explanation.
I don’t understand for a microsecond why it is important to translate Adam as simply man. We continue to use phrases today like, “until man developed tools” to describe all of mankind. And let’s go to Romans 5:12
“Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:”
“by one man” It doesn’t get any clearer than that.
God bless,
