Sorry about the way I phrased my last post, I didn't mean to come off like a dik, was just in a hurry.

There are several fallacies with Pascal's Wager. For one, it assumes that the only two options are atheism or christianity. It doesn't take into account the numerous other religions that have been created by man. Believing in one religion typically indicates that this person does not believe in another religion. How can you be sure your religion is the correct one?

It also assumes that there no cost to believing in god when in fact, for the most devout believers, they spend a significant amount of their time either in church or doing things related to their religious beliefs. These people are also usually the ones contributing money the church. So believing in god typically costs someone time and money.
