Most people believe all sorts of stuff - simply because someone has told them. You probably believe in gravity, why? Are alternative explanations possible? You probably believe in evolution, why? Or perhaps you believe in some religious texts, again why? Did you verify anything? You probably believe in h2o, why? Have you put hydrogen and oxygen gases together to make water? You probably don't believe in the aliens we saw in the film 'Independence Day', why? Is it because you were told it is fiction? You probably do believe the world is getting warmer, and that we are in danger of a mass extinction event, why? How was this proven to you? If one scientist says something, is that proof? If 100 say the same thing, is that better proof? Etc. What measure do you use to filter the truth from noise, lies and reality? Is it just what you are told - do you doubt your lying eyes? Or is there internal discernment and primary experience is the gold standard?
