I have & it is what I believe. If you believe otherwise then it is up too you to prove it.
It's not up to anyone else to prove/disprove your belief.
Whether or not your belief is based on facts, evidence and rational arguments is another thing altogether.
Saul of Tarsus believed that Jesus was the Messiah - despite having once thought otherwise. Jews and Gentiles argued with him and he spent many hours in debate, giving them facts and backing up what he said from the OT Scriptures. As a result, people were converted.
You don't believe that men walked on the moon, but all you have to back up your claim is "it was faked, Dean Odel says so and here is a YouTube clip I have found."
You don't believe the earth is a globe and all you have to back your claim is "it's faked, and here is a YouTube clip I have found."
Now you are being given information about satellites - from someone whose work involved satellites - and all you can say is, "here is a summary of a YouTube clip I have found."
If you don't know, then why would you not trust people who do?
If you haven't been somewhere - the Antarctic or the moon - why would you not trust people who have?
It's like if someone said "I've never been to Wales so I don't believe it exists - and it's obvious the language has been made up."
