As Kit and Chad said, atheism isn't generally a positive belief ('I believe that gods do not exist') although this is occasionally the case. Much more common is the position, 'I do not believe the gods exist', which is referred to as negative atheism.
For myself, I lack belief in gods because there is no evidence that they exist, and the arguments for their existence are not at all persuasive.
