Aliens almost surely exist, but the way they're presented in tv shows like ancient aliens kinda makes me raise an eyebrow, the interesting debate got reduced to sensationalist, psuedo-scientist TV slop, engineered to make their viewers feel like they belong in a huge international conspiracy that very few people are aware of, basically, aliens became a marketing ploy used to generate revenue for a few struggling tv channels and websites, if you look at images of Roswell today, you'll know what I'm talking about. It's not a bad thing to make money from this fascinating topic, but the ridiculous extend some third parties have reached in the name of the godly money printer, has really put me off. I know this first hand, my dad has been a hardcore Ancient aliens Fan for 10+ years and the topics discussed in the show are just beyond ridiculous.
