Just curious, Mark. Where do you draw the line? What do you believe? Do you think they roll up the sidewalks two minutes after you walk by? Is it all put on just for you like in that Jim Carey movie "The Truman Show"?
You mentioned Tesla in another of our conversations. I assume you mean Nikola Tesla the engineer and inventor. What if I told you I have secret knowledge that he NEVER EXISTED? He is a fictional character. How could you prove I was wrong?
You've been to Croatia and saw the house in which he was born, saw his birth certificate in the local town hall? All fabricated just before your arrival. You read his biography? A work of fiction. Don't tell me you read a Wiki about his life and accomplishments, there's one that describes Einstein's ideas as well, all bullshit, right?
Anything you know about Tesla you got from some source not independently verifiable by you, and yet you choose to believe it.
Why not the moon landing or the Mars rover or the Juno mission?
Two questions you have to ask yourself; how many people have to be lying in order for me to be right? What will I accept as proof?
