You don’t believe in continental drift, or plate tectonics?
No.
In fact when I was in college (RPI '68), some speaker came to give a talk about this stuff and he was considered a quack.
Also, there's a big difference between continental drift and the notion that there was a time when there was only one land-mass while water still covered two-thirds of the planet. You sorta have to explain how it got that way; not that the explanations of how the earth formed as we see it are any good either. (E.g.: tell me what the earth was like when it was 7000 miles in diameter, assuming you believe it accreted and it was 7000 miles in diameter sometime.)
