Then the next questions are going to be:

Why? Why would they lie?

And

How could they keep it a secret?

If you want to believe we landed on the moon , that's awesome, you are entitled to your own beliefs, but to refuse to look at any credible evidence before dismissing it is just ignorant. It can be hard, trust me I know, I was a slave all my life, and the funny thing is no one cares, we all just carry on blindly.

Remember when Pluto was a planet?

Yea turns out after 500 odd years they were wrong, it ain't a planet, sorry. But everything else we tell you is right tho. Trust us.
