We know all of the buildings, cars, and other things in this world have been constructed or manufactured by someone and none of them were the result of a coincidence of nature. In this same way, the universe and the earth were created by someone. It is God the Creator who created the heavens and the earth. The Bible is the Word of God the Creator. It clearly tells us where we came from, why we live, and how we should live. Solutions to all kinds of problems in life are included in it.
"...you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus." (2 Timothy 3:15)
