Species – A group within a genus that is reproductively isolated and unique from other groups. I cut a lot but the URL's are posted for verification, and reading. A person can have either blind faith in the bible story or ask yourself does the story defy logic & common sense. Animal Species 6.5 million species found on land and 2.2 million (about 25 percent of the total) dwelling in the ocean depths. https://www.sciencedaily.com/releases/2011/08/110823180459.htm Bird Species the American Museum of Natural History suggests that there are about 18,000 bird species https://www.amnh.org/about/press-center/new-study-doubles-the-estimate-of-bird-species-in-the-world Insect species Conservative estimates suggest that this figure is 2 million, https://www.si.edu/spotlight/buginfo/bugnos Animal,bird,insect species into the millions. Completely exclude the 2.2 dwelling in the ocean depths. Now lets look at the bible version of the arc size The Bible gives the size of Noah's Ark as 300 cubits (507 feet) long, by 50 cubits (85 feet) wide and 30 cubits (about 50 feet) high. Then look at the two versions of the quantity of birds & animals on the arc. http://www.hcna.us/columns/noahsark.html Naturally I wondered about plant life surviving salinity & lack of oxygen. The rains came for forty days and the waters covered even the mountains and all flesh on the earth died. According to J the flooding lasted 150 days. The explanation I found. https://answersingenesis.org/the-flood/how-did-plants-survive-the-flood/ Right in the middle of the explanation was this. Every year, rivers and other sources dump over 450 million tons of sodium into the ocean. Only 27% of this sodium manages to get back out of the sea each year. As far as anyone knows, the remainder simply accumulates in the ocean. If the sea had no sodium to start with, it would have accumulated its present amount in less than 42 million years at today’s input and output rates. This is much less than the evolutionary age of the ocean, three billion years (emphasis original). So the article author doesn't refer to the bible version of creation being 6000 years. The last sentence clearly says "the evolutionary age of the ocean, three billion years" No doubt in my mind the story of Noah & the arc is nice but when it comes to the millions of species loaded on the arc. I just can't envision that as possible.
