The main reasons for me is the lack of demonstrable evidence, reasoned argument and valid logic to support the existence of a god or gods.
In other words, the claim that a god exists put forth from theists has not met its burden of proof.

You'd believe if you just opened your heart" is a terrible argument for religion. It's basically saying, "If you bias yourself enough, you can convince yourself that this is true." If religion were true, people wouldn't need faith to believe it -- it would be supported by good evidence.
