[quote]spend their entire lives devoted to this, and don't just read what someone said and believe it.[/quote] I like that you chose the word " devoted ". What basis are you claiming that, the scientific community don't engage in blind faith? ... Is it because, someone told you? I doubt every scientist actually tested the laws of thermodynamics for themselves, before using it in calculations of their own personal theories. It's an extreme example, but an example, nonetheless.
