Your right Jackeron we are not born Christian or Muslim, for in the Fall in Genesis Chapter 3 all men are separated from God until you are reconciled to him.
Ultimately all through the Old Testament we see God redeeming His people until ultimately He sent His son Jesus Christ to Die to take the penalty your sins and mine. If you believe in the Son of God your sins are forgiven in Him.
Regarding creation, the creation itself testifies of a creator, God Himself says this and our own experince lets us know, this is called general revelation.
Psalm 19:1 " The heavens declare the glory of God, and the sky above proclaims his handiwork."
Romans 1:18-20 "18Forthe wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19For what can be known about God is plain to them, because God has shown it to them. 20For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse."
Special revelation is Scripture itself the bible. this contains the very word's of God himself. the God that spoke the bible is the very same God who loves, . He is the God who seeks after you, He loves you! In Jesus Christ you have this fulness of Love who died for you and rose again so that you may have eternal life.
