If the entire planet was flooded, then nothing could have lived and the survivors would have to have inbred with each other to repopulate.
Which is what they did. Plants’ seeds survived.
You really need to read the entire linked article for answers to your objections.
The original Hebrew allows for the flood to have been a localized one.
So in your beginning of the human race, thousands appeared all at once to prevent inbreeding?
Fish & sea creatures could have lived. They didn’t need Noah’s ark. I guess birds could only survive on the ark; because of exhaustion after a few days of just flying around. Noah’s sons didn’t have to inbreed; they had wives who weren’t close kin. Animals lived on the ark. - Things back then were very primitive. If people got bored; they had the same loincloth to get unbored in. Earthworms wriggled in two by two. - As time went on, new & improved animals showed up on the scene, dogs sprang from wolves & the rest is history. Twinkie is kin to one of those people on the ark. It’s evident!
You mean like before the fool too?
Read this and it will change your mind.
