Jzyehoshua needs to show us actual evidence that the remains of an actual boat were found, and then, how it somehow refutes all the evidence that science has observed of the processes that led to the modern world.
Yes, indeed, he does need a lot more info on his boat. He's not going to get any, of course, so don't expect much.
But this is a somewhat interesting geologic formation that some post doc might want to take on. It might be a caldera, a crater, the remains of a crashed alien spaceship, or tectonic shift. I’m hoping on the spaceship, like Jzyehoshua is hoping on the boat. Gotta wait for the real geologists to chime in, though.
Go Team Spaceship!
Eschew obfuscation. Habituate elucidation.
