Heh heh, the videos on that site are hilarious.
The statements on the first video are classics. "Priests of the science religion claim that moon phases are caused by the shadow of the Earth. No they don't.
"The Michelson-Morley experiment proves the Earth doesn't rotate". No. It proves there is no luminiferous aether.
Do they explain what sort of weird physics were involved in forming a flat earth-sized object in zero gravity out of floating space rocks?*
* I don't want to explore their web site in case it helps generate revenue for them.
From the comments re space ("so-called space") I gather they don't actually believe there is any 'space' as such, and that the Sun is a lot smaller and closer than it really is.
After the stupidity of the 'as any fule kno scientists claim moon phases are caused by the Earth's shadow' (no they don't), followed by "if that were true moon phases in Winter would go backwards' (why?) I gave up watching. There is amusingly stupid, and then there is interminably stupid.
