What was here before God? What "caused" God?
[edited to add: this is not an attack upon any religion only a observation on the southern/traditional school of Buddhism. This is in fact also not an endorsement of Buddhism. Any reproduction of this portion of this tread is reserved. Objects in the rear view mirror may be closer than they seem.]
