I don't see how that follows. Feynman, who wasn't an MWI enthusiast, clearly argues that no human observer is necessary to perform a quantum experiment. If the detector is designed for a which-way measurement, the interference is destroyed. This shows the lack of necessity of a human observer, a point I've made several times but apparently you didn't read my comments carefully.

You have misinterpreted and over-generalized the results for a class of quantum experiments and observations which manifest interference effects, such as the double slit. I've already explained it. Do you know what a QUANTUM experiment is? Is the Earth-Moon a quantum experiment? If so, where are the INTERFERENCE effects?

Not an isolated system. Unrelated to double slit results which, as I CLEARLY explained, is the cause of your MIS-interpretation. Your claim only applies in a special situation of quantum experiments which manifest interference effects. Next time you want to make claims about my position, please read what I have written.
