>...you wouldnt see mainstream tv shows

yes, you would. its called poisoning the well to get ahead of the narrative. 85% of the shit mentioned on Ancient Aliens is hokey bullcrap that doesnt even sound plausible in fantasy. 
this is used to associate that remaining 15% with the schitzoids. Automatic association is made in the brain between crazy tin foil hat conspiracy retards with pirate radio stations in the normie brain the second aliens or reptilians are brought up, this isnt an accident and it isnt natural. 

the absolute ABUNDANCE of evidence short of a ship landing on your lawn is staggering. there is more evidence of ghosts, bigfoot, aliens and other cyptids than was ever presented during the Nuremburg trials of the extermination of jews.

The sheer mass of charlatanism surrounding it is why the occult stays the occult in the age of information. 
Nothing is hidden, the only real test is being able to sort through all the bullshit.
