Agreed. Way back, including collapsed walls at a time period consistent with the biblical story. Like so much of the biblical canon I consider the story as much myth as fact, but many biblical tales appear to be based in history that is occasionally verified. As most is pre-Roman I won't go into any of it here, but the old testament certainly has a lot of facts on its side right down to the order of creation coinciding with the order of evolution and the early Earth being "...without form, and void." I find those who seek to dismiss it to be non-objective, and those who need proof to believe it to be of little faith.
Just the facts, mam, as Joe Friday used to say.
