We know that the universe has a beginning and an end. So it is unlikely that the universe just always existed. I think that it's the most logical conclusion that there is a timeless and infinite source of energy outside our finite universe that created it. In other words, God.
Now this tells us nothing about God. Does he have a personification, or is He just mindless energy? What is God's nature? But it all boils down to: Does God love us? If He does then He would let us know. The Bible tells us that God loved us so much He sent His only Son to die for our sins. Sounds like God's love letter to me.
The alternative is to believe in a God without love, and a world without hope of salvation. I choose to believe in hope and love. Christ is the answer.
