Evidence that God exists: He has a house just up the road from me. It's a good place to go on Sundays and Wednesday nights. Jesus is there all the time, because "Where three or more are gathered in My name, there am I, in the midst of them. The Holy Spirit evidences itself as well in the lives that are changed there. God isn't hard to find. Go to His house and ask for Him.
Evidence that Satan exists: We aren't ALL at God's house on Sundays. Things come up. Satan throws many obstacles in our path to keep us from going. We get into such a hurry we eat without asking a blessing on what we eat. We see Satan's handiwork in the satanic religion of Islam, which leads people by the billions to eternal separation from their Creator.
Evidence that atheists exist can be found in these forums, where those who refuse to acknowledge the supremacy of the Lord come here to preach their own religion of naturalism and pass off their beliefs of evolution as scientific fact.
