No matter how smart or well-educated you are, you can be deceived.

No amount of belief makes something a fact.

Blind belief can be comforting, but it can easily cripple reason and productivity, and stop intellectual progress.

Science is a search for basic truths about the Universe, a search which develops statements that appear to describe how the Universe works, but which are subject to correction, revision, adjustment, or even outright rejection, upon the presentation of better or conflicting evidence.

No evidence against a firmly-held belief, no matter how good or abundant it may be, will sway the true believer.

Religion is based upon blind faith supported by no evidence. Science is based upon confidence that results from evidence - and that confidence can be modified and/or reversed by further observations and experimentation. Science approaches truth, closer and closer, by hard dedicated work. Religion already has it all decided, and it's in the book. It's dogma, unchangeable, and unaffected by reality and whatever facts we come upon in the real world.

Heroin also makes people feel better, but I wouldn't recommend using heroin.
