Background: I am 40 years old, and in my entire life the only face to face eyewitness event that I can remember where humans actually observed an attempt to fly into outer space, the craft exploded and showered its fiery remains - including 5 dead astronauts - down over the Earth as soon as it reached the atmosphere. I have seen no other real eyewitness evidence.
As an Australian, I also live really far away from any launch or landing sites, with all of them too far to be directly observable even through a powerful telescope. I have never witnessed any space exploration endeavors in person and all I have available to me is accounts by other people that I have never met in real life and videos on the Internet or recordings and interviews on the television or radio stations.
Question: How could I go about finding proof of mankind ever reaching outer space first hand, with astronauts doing moonwalks, spacewalks, whatnot when all of it seems unreal, happening somewhere else and never directly touching the grounds of my own country, which happens to be a whole continent of the planet Earth that I live on, while only having indirect and anecdotal evidence of it? I would take a word from any of you that have been a direct eyewitness to human space exploration, but preferably ask of you for any idea how I could prove that by holding something in my own hands that could only exist if that was true, or by doing my own direct observations, be an eyewitness myself and have proof beyond reasonable doubt?
Is there any direct evidence of human space exploration that nobody on our planet could dismiss as circumstantial?
