Do you think that part might be an allegory?
I don’t think so. Reptiles need to spend at least PART of the time out of the water...

Gotta love when the Bible says “with God all things are possible” and then science provides an example. As Genesis states, God did use the water under the mantle to flood the earth.
Realizing skeptics & atheists will deny even the remotest possibility. For believer’s it only adds more breath to His magnificent creation.
I think it is God's way of telling low-tech people about massive geologic change, asking them to accept the details on faith.
The fact that science keeps discovering things which confirm what people of faith already know-- such as the existence of vast stores of water deep in the earth-- should not be a surprise.
"Remember, dear brothers and sisters, that few of you were wise in the world’s eyes or powerful or wealthy when God called you. Instead, God chose things the world considers foolish in order to shame those who think they are wise. And He chose things that are powerless to shame those who are powerful."
--Paul's first letter to the church at Corinth, 1:26-27
