You are assuming at least the following:

(1) God either cannot discern between a faker and a sincere believer, or he does not care,
(2) God actually cares about who believes in him, and will enact retribution accordingly,
(3) There is no chance religion misrepresented God because they need believers,
(4) We are willing to sell out to God in order to obtain a reward for ourselves,
(5) We are not concerned about damaging society by sustaining fraud,

I do not believe or accept any of these assumptions. Frankly, if there is a God, I believe he would:

(1) Understand sincere disbelief,
(2) Prefer sincerity,
(3) Not care about who believes in him,
(4) Be upset at religions that use his name to obtain believers,
(5) Be disappointed at those who sustain religion,
(6) Recognize his own role in our disbelief,
(7) Like science enthusiasts,
(8) Want people who stand up for morality and who will not sell out for phony promises.
