2 of every species on one boat would be a logistical nightmare and would take decades to scour the earth and capture, feed, cultivate the millions of species on earth. Even today, with all the resources at hand, it would be impossible to achieve without many of them dying. How did they know how to nurse the dinosaur babies and what happened when they rapidly grew during the flood?
I'm confused.
Eugenius,
You seem to be a little confused about details.
Noah's Ark was around 450 ft long, 85 ft wide and 45 ft High. This amounts to over 51/2 million cubic ft of space to store things. There would be plenty of space. This is more space than in most large trains.
Another discrepancy; there were 7 clean animals, and birds, and 2 of the unclean animals, Gen 7:2-4.
The reason for the 7 of the clean was so that Noah could use one for a sacrifice, Gen 8:20.
Only each KIND was taken. You would only have to take 2Dogs, 2horses. 2 elephants etc. Not nearly as many as people might think.
Remember, God helped Noah to load the animals, and Noah had seven days to get them into the Ark, Gen 7:4,10.
