Ah, you were reading that literally?

Any real proof?

Sorry, but I'd add a longer comment only Santa Claus, the Easter Bunny and the Tooth Fairy have just dropped by for coffee....LOL.
And IF that ain't enough now the Yeti and her cousin, the Bunyip, have arrived as well....LOL.

He’s lucky a Great White, Tiger or Bull Shark didn’t grab him.

Packard had scuba gear on so that might be used to draw distinction of time reaction. I think we have to find another narrative which challenges Christianity. Try this one:

Just for the sake of argument , there are several different kinds of whales . I would think that being inside of one , even briefly , would not necessairly be the same as being inside of a different kind of whale . Two , if you're in pitch blackness for a long period of time , how will you know how many days or how much time has passed ? I don't believe there was a reasonable calendar a few thousand years ago , that he could check to see if , "Well gee , I was swallowed on a Thursday and now it's Sunday ." I would also suspect that how a whale's digestive juices work on the human body would depend on what that particular whale's normal diet consists of . Some whales have teeth , some simply strain grill out of huge amounts of sea they swallow . So , at this particular point , I don't see that anything has been proven in any direction , beyond the fact that a man's body was actually able to be taken into a whale's mouth , and also be spit out again and he survived the experience .

Because he found it a little too cramped in there to have lunch?

Why would they say "there's so many flaws" and then not list them? They didn't even give you any background info so that you might be able to figure out what those flaws would be yourself.

Nothing is needed to disprove myth and/or nonsense.
