Assuming for a moment that a worldwide flood actually happened 5,000 years ago as described in Genesis, I'm pretty sure that Noah & Co. would have had alot more important things to do. Like shovelling all the (literal) shit from human and animal alike fro the ship every single day. Plus they have to feed all the animals and cook for themselves every day. All the logistics that would have been involved would have been mind-boggling to say the least and would have taken a lot of their time. I sincerely doubt they would have had time for a frigging "Family Night" of worship.
Good lord, the Writing department gets crazier with each new picture they submit.
