Hold on, Bible Chronology put the Flood roughly around 4,000 to 4,500 years ago.
This begs the question: what modern scientists are doing the research? Basically, no one. "Modern science" operates under the assumption that a Global Flood isn't
possible, end of story, and they work from there.
The question that should be asked is: "What kind of affects would it have on our planet and what kinda of evidence would it leave behind", then you start generating questions and theories that clash with your "modern scientists", but I don't think your evolutionary-minded thinkers are gonna put their careers on the line to challege a world-view that is opposed to Biblical fairy-tales.
The falseness of the Biblical Flood has been deemed unchallengable for the past century, so sorry, your "modern scientists" haven't even
looked for possible evidence.
This is why I don't bother to argue about the veracity of the Flood story, and will not....and I did expect you to reject it out of hand like you did.
Thanks for the response, though...but I am done with the topic of the Flood.
