Because the physics works out. On the high altitude flights they got to orbit - _then_ rendezvoused with a target vehicle and used the target vehicle's engine to boost them to a higher orbit. This was practice for Apollo's Lunar Orbit Rendezvous plan, and a test of heat shielding for higher speed re-entries.
You read that this happened but how do you know that it really happened?
The capsules were tracked by radar in various countries. Triangulation verified the height.
Same as above. How do you know there were no secret deals with other governments made behind the scenes?

In crucial respects, then, the Cold War was a kind of tacit arrangement between the Soviet Union and the United States under which the US conducted its wars against the Third World and controlled its allies in Europe, while the Soviet rulers kept an iron grip on their own internal empire and their satellites in Eastern Europe - each side using the other to justify repression and violence in its own domains. The Cold War even had a
cultural component, with rival interventions in the art world.

over whelming global multi national scientific data surely tilts the scales a little.
Same as above. Lot's of stuff that we read is all lies.

We are not in a position to be able to confirm if the Gemini craft went up as high as we were told they went and documents that say they went up to over seven hundred nautical miles are not proof that they did so.
There's no reason to simply believe this.

Gemini 11 set a manned Earth orbital altitude record of 739.2 nautical miles (1,369.0 km) in September 1966, using the Agena target vehicle's propulsion system. This record still stands as of 2017.

You people have a naive willingness to believe when you read official info and an a priori incredulity when you look at hoax evidence. An objective truth-seeker has neither a naive willingness to believe, nor an a priori incredulity.
