For someone who esteems science as the be all and end all why so many quotes from arts majors? Anecdotal one line quotes from a bunch of arts majors proves nothing.
The closest Webster's definition to any of these is:
firm belief in something for which there is no proof
There is a difference between no proof and denial of proof. As there is no scientific proof that God either exists or does not exist it would seem that faith is required for either belief according to Webster. As you seem hung up with science, why not see what scientists actually believe - wait a minute someone already did that. In 2009 Pew Research looked into this and determined that 51% of the polled scientists believed in God or some type of higher power, 41% did not believe and 7% did not know. So it seems the team you are trying to back is fairly evenly split - hardly compelling.

The one thing i will grant you is that disbelief in God is much higher among scientists than the general public but still nowhere near high enough to even suggest belief in God is illogical.
I have no problem with anyone believing God either exists or doesn't. Myself I'm in the don't know camp. What does irk me is someone like you who boldly proclaims the issue is settled and looks down on anyone who does not subscribe to your belief as ignorant or illogical. It seems you have placed fully half the scientific community in that category
