Ok....
The main issue with newbies to the FE model that want to believe FE basically need to realize that their mind has been wired to think in a Globe model only.
The programming is strong.
"Planets", "gravity", "stars", etc.. are all real, but they are NOT what mainstream science tells us they are.
Instead of asking how do you explain planet footage, assuming that if a planet is there it contradicts FE, you should ask, what really is a "planet?"
We may not know for sure since Flat earthers are mostly civilians that don't have very advanced equipment, but try to think outside the globe.
Just because a planet looks spherical it doesn't mean that it is a planet like earth would be a planet.
Its like saying: If a basket ball is a ball, then why is the court flat.
