He asks: “Riptides are another significant hazard to humans. Riptides actually killed almost one person a month in California recently. They are difficult to detect and equally difficult to predict with any accuracy. Are these natural as well, or a result of interloper manipulation?” What can Creator tell us?

Here, too, both things can happen. There is turbulence at times in ocean currents for a variety of reasons, because nature has complexity consisting of multiple forces, sometimes working in conjunction and in parallel, but sometimes working literally at crosscurrents with one another. But, like weather of all kinds, the interlopers can potentiate a tendency to make it excessive and destructive beyond what would happen normally, and they do this on a regular basis with ocean currents just to be mean, and if they see conditions brewing that can be manipulated to cause harm, will often do so, just as a human seeing an ant on the sidewalk might decide to step on it out of disgust for that lowly creature. That is how the extraterrestrials regard human beings, no better than other lowly organisms in their estimation.
