I love that you said dry/wet moon. I grew up in the Cayman islands and an old fisherman told me when the crescent moon is on the side it's going to rain cause the moon is tipping out it's water. And when it's on the bottom it's holding the water so it won't rain.

Weirdest part is it seems to be true most times. Lol

It can be both depending on time of year and where you live.

How about being able to see other planets through an amateur telescope and even some of their moons? Or how would satellites work? Or why the hugest undertaking ever to cover up the fact we are inside a planet when it would have just been part of our natural history...

Lots of Logical disconnects in the hollow earth theory. Especially the fact that It probably would collapse under it own weight...
