Satan Powerless

Those fires in Los Angeles came 24 hours after some people in Hollywood mocked God and the audience were laughing. They didn't think it was funny when their homes burned down. As far as the other one Satan didn't do it because if he did then he was defending God and there's no way he would defend someone who casted him to Hell. 

Satan & Posesidon

Both are fake when it comes to what is written here both do not have supreme powers that God only has. It is clear in God's 1st Commandment.
