Earlier quoted context omitted.
The oceans used to seem really big to us too, but each rising tide wasn’t destined to continue rising—the tides turned out to be cyclical, even though we couldn’t imagine anything but gods or magic to be powerful enough to cause the change. Perhaps we’re in a similar trough of understanding here?
I'm not sure I get your point, are you saying the moon and the sun, the things we now know cause the tides, are small things?
> The reason tides always rising is plausible if we see tides rising now is simply that's it's far more plausible nothing so special ever happened as to change the motion of the entire ocean.
> The ocean is not a little trickle of water down the wall in the bathroom you can easily redirect with your little finger, the ocean is really big, so you need something equally big to make it change behaviour.
