Yes, there is a God.  Have you ever looked at the clouds? The mountains? Or observed an animal giving birth? All of nature testifies to God's existance.  However, there is no proof great enough to prove God exists to those who do not want to believe it. Jesus says as much in Luke 16:31. Regardless of natures testimony, God reveals Himself to us through the Scriptures, His Word to us, that we might grow in faith and come to a closer relationship with Him. Please take the time to read what He has to say to you!
