Mate, I'm kidding. Not that I can honestly prove it either way

Ha, fair enough! At least you’ve got a good sense of humor about it. Cheers for the laugh!
Life is too short for drama 🇬🇧🚒😎
Actually that video proves it.
Another way to prove it for oneself is to take a photo of the sun at noon with a solar filter. And take another one in the morning or evening before sunset.
The sun will be the same size in both photos.
If the flat earth model was an accurate description of reality the sun should start as a spec in the morning, grow in size throughout the day, be its biggest when right overhead, and then shrink to a spec again in the evening.
Don’t trust my word for it. Verify for yourself.
