Edward's pretentious claims of Alchemy's extremely over-reaching scope of power are both ridiculous and idiotic (as he will soon come to learn); but it bodes a strong question nonetheless:
Why are scientists so hell bent that their speculations are 'proof' and religion's speculations are 'lies'? They have nothing more to back their claims up than a religious person does theirs.

And where Edward's abilities are so close to magical, the fact that he can say with a straight face that it's science makes me wonder just what kind of cigars they pass out at the Academy. In addition, just what is it that drives Edward to be so blatantly vocal on the subject, something you never really hear any of the other Alchemists so verbose on? Perhaps Edward is angry at God and believes he could have saved their mother and Alphonse's body from destruction? Maybe Edward believes there is no God because his actions brought him to the pinnacle of God where stood and faced God's power, and vengeance at the Forbidden Gateway.

Whatever the reason, it seems that Edward's search for the Stone was akin to a person's own search for God. And in some cases, we really don't like what it is we find there.
