What about all the photos and videos from space that show the Earth is round? How do you explain them?
These are clearly manufactured by NASA. Surely you can do better than that?
I can do better.
Between the space agencies of Russia, China, India, Japan, USA, Europe, and the private efforts of independents from (at least) the USA and New Zealand, humankind has notched up over 70 years of manned and unmanned orbital space flight.
The presence of manned and unmanned orbital craft is verified on a daily basis by organisations and individuals, professional and amateur, from pretty much every civilised country on Earth, who;
- Monitor the orbital tracks of those satellites for geodesic purposes, sometimes purposes independent of the purpose of the satellite
- Download data from those satellites, for a variety of purposes; scientific, commercial and recreational
- Upload data to those satellites, usually for news-gathering, broadcasting, or commercial communication
- Navigate using data from those satellites
- Receive TV and radio services from them
- Observe the satellites by eye or by telescope, sometimes simply for the pleasure of doing so
- Maintain the orbital tracks of those satellites, and operate them, as a commercial enterprise providing services to others
If these satellites were not actually in orbit around a globe Earth, someone in one or more of the above groups would have noticed by now.
