Anyone know when the earliest reference for a globe earth was?

The Old Testament has quite a few...

That's a laughably bad video. It's the usual thing where they basically expect you to believe them just because they say it, but they'll back up their credibility by showing you an example of something else that apparently looks to be true, but is based on a camera's optical illusion or something similar, while they don't trust the cameras when GE's use them.

He lobbed a cotton ball that claims that the moon makes the exact same shadows as the sun, while offering no evidence.

He left out the consideration of certain variables such as the size of the system in question. When considering local light on a small scale, lets say within reach of a human or maybe even 500ft away, the light rays may be assumed to be parallel depending on the nature of the experiment and the precision required. But when considering a system that contains the whole earth and moon or sun, obviously the light rays are not parallel, and even the slightest change in angle has a great effect. The precision needed for that system is much higher.

The sun and moon can only make the exact same shadows when the results match up no matter the level of precision involved. But it's just a confused mess using the parallel light "paradox" as a decoy or strawman or whatever, when in reality things aren't always so simple, and distinctions need to be made. Based on the size and distance of the sun and moon, both radiate light from a large radius that illuminates much of the earth, while appearing almost perfectly parallel at any location on earth that can be observed by one person.

He then deceives with his spotlight demonstration that the sun and moon can't have parallel light because you'd be blinded like the camera when looking directly at them instead of seeing a circle of light, even though he first adds the condition that spot lights don't have perfectly parallel light (so why would the sun or moon need perfectly parallel light to act like they have parallel light?). Whether you are entirely blinded, partially, or can clearly see a circle of light all depends on how bright the source is in comparison to the properties of the light the sensor (our eyes or a camera) based on sensitivity, dynamic range, and aperture size. The morning and evening sun is notorious for blinding people while driving unless they use a visor or sunglasses. What makes a spot light a spot light is mainly its high intensity compared to the surrounding light.

You make a fair point about cameras. They can be easily used to deceive or misinterpret. FE's claim it's the camera's fault if the curve of the earth is seen, but they expect GE's to believe whatever footage apparently supports FE.
