I've always thought that 'Noah's Ark' is the correct one, not 'Noah's arc.'
A friend of mine who speaks English quite well claimed that
native speakers do not distinguish 'arc' and 'ark', which I didn't buy.
Then, I chanced to see this expression, 'Noah's arc', an American cable television dramedy, from here :

And I got confused.
Did they get the name changed on purpose for certain reasons?
Or was my friend right?
Are those two words interchangeable occasionally
or is it still generally considered as an error by most?
Thanks for reading.
I'd be looking forward to any of your comment.
