I think you underestimate the impact space travel had on the collective consciousness of the part of humanity that was aware of it. What you flippantly dismiss as diversity wasn't a thing back then, not like it is now, and both the reality and the dreams of spaceflight - even unmanned - brought with it a strong sense of the whole world being one people. To prior generations that was almost unfathomable.
