...and used Chamber Pots? also to flush a chamber pot, could you use your faith like a mustard seed to like teleport the stuff into the ocean? (Luke 17:6)
I'm an atheist and even I find the question offensive. Firstly flow toilets were known and used before C.E.
Secondly what do toilets have to do with faith?
They were very old school and mostly just $hit wherever it wasn't going to be in the way. Sanitation wasn't much of a problem yet because the population was still very low.
God isn't a genie who magically does everything we tell him we want. But that's what you're implying. If everyone got exactly what they asked for from God every time they asked, the world would descend into chaos - even worse than the present chaos.
