Prove me wrong.
Did you see the Titanic sink?
Then how do you know it sank?
Underwater video? Pshaw. We all thought we saw with our own eyes on TV the Twin Towers being hit and pancaking on 9/11 but careful, intelligent students of the footage were able to figure out it was a controlled explosion by the government.
TV? Like the TV images of Neil Armstrong and Buzz Aldrin walking on the moon?! That never happened as we know now. Proven to be a Hollywood stage set.
The Titanic never sank.
