What other "unknowns" do you not believe "against?" Tooth fairies? Gremlins? Flying unicorns? After all, they are unknowns. What to do with them?
ditto.
This whole beleiving the unknowns is no less legit than beleiving against the unknowns is really the mark of a person engaged in delusions and idiocy.When you have no legit argument you can always come up with some stupid wannabe existential psychobabble crap like this.
Conform your beleifs to your reality NOT conform your reality to your beleifs.
