Yes, Satan is real and that's why all the bad things happen on earth.The Bible has clearly shown us how Satan came to exist. If it weren't for Satan, then I don't think we could be having hard times living on earth. According to my understanding, I am trying figure in a way, all the earthly evil things happening on earth are as a result of Satan. Satanic acts like murder,corruption, prostitution are condemned in the Bible but are happening on earth because of the powers of Satan.
If Satan didn't exist, then we couldn't be having satanic churches and also the existence of Illuminati. Satan also needs followers and that's why he's giving away all the riches so that people can turn to him. Satan is real and no matter how much am convinced he doesn't exist, I won't believe it.
