The best way to determine that there is no god is to look at all the material evidence for a god. There is none.
If your aim is to create a logical and/or philosophical argument, the best bet is to put the meaninglessness of god on display. Due to the fact that there is no direct evidence, and any claims of physical evidence will be put to the test and fail, 'god' will never amount to anything more than a vague concept which describes a non-entity.
