Cameras showing earth curvature are false?

[Lawrence]

Hi - I am inundated with those who claim the earth is flat and I keep asking for confirmation as I like to keep an open mind to things. So far, everytime there is a high altitude ballon pic showing curvature, the Flat Earth pundits claim it is due to Go-Pro distortion etc.

Could one you experts help this layman please?

The earth is not flat, and no HAB flight should be required to convince people of this accepted fact. GoPro distortion is a red herring. I do not humour the flat-earthers by allowing them to state their case. We must fight post-truth on all fronts, and engaging in a debate over known, provable, scientific facts is not helpful.
