There’s nothing modern about bitumen and here’s my “inside” information:
“The Judaicum Bitumen is a famous deposit of native asphalt seeping through diapirs at the bottom of the Dead Sea, which comes occasionally to the surface through seismic activity in blocks of up to 100 tons in weight which are more than 99.99% pure. It was the object of the first known battle for a hydrocarbon deposit, between the Seleucids and the Nabateans in 312 B.C.[6]”

In other words you can’t produce any evidence from the Genesis text that the ‘kopher’ mentioned has to be bitumen pitch and black, rather than conifer pitch and clear.
My point is simply that your pretense to know that the ark can’t look like the dutchman’s replica is just that, pretense, based on no real knowledge. Maybe if you look hard enough you can find a second door on that replica to save your sorry record.
