Bet you can't prove Star Trek isn't real.
Bet you can't prove it is.
I have seen it with my senses, they tell me it's real (argument used by flat earthers)
I have seen actual star fleet uniforms and phasers, they really exist and are tangible objects (better argument than any used by flat earthers)
The star ships depicted in Star Trek can travel using warp drive technology - they can reach other planets quickly, therefore warp drive technology must work (argument used in several variations by flat earthers to describe many things)
I don't see Klingons invading earth, therefore Starfleet must exist to protect us from them.
Therefore that constitutes solid proof that Star Trek is real.
