In context, nothing survived but Noah, his entourage and whatever and whatever animal life was on the Ark. There are posters in these threads who have provided the exact date of the flood and it was apparently only a few thousand years ago. If you disagree, how do we resolve that disagreement?
Do you care that some people only go as far as algebra in learning about math? No calculus, no physics, no trigonometry or advanced functions? I haven't a problem with people who choose to believe the entire planet was flooded and that Noah had polar bears on the ark. It merely tells me how well or how long they studied the story. Is their limited knowledge causing any more trouble than do people who stopped learning math after algebra? I can tell them what I have learned, they may have an interest, they may not. The question is whether the information should be readily available. Or, should we leave the stage only to those who believe in a planet-wide flood?
