God is the reference, He is always in our thoughts, and we have two alternatives: to accept Him or to spend all life trying to self persuade He is not necessary.
If God would not be full of love, maybe He could have created us and leave away, letting us believe He is not there. But, in His infinite love, God does not desist to show us He is here, with us, loving us inside and outside.
Some people have studied and learned a lot of science, but until today nobody can explain simple things like out life, our feelings, nature perfection, and so on.
Starting on God, everything makes sense and we can live in complete harmony with all the World, aware about out limitations, but with all faith God will provide what is out of out capacities.
In God out wills are listened and His love guides us to Paradise. Prayers are not word to wind, but He listens everything we say and hold all in His lovely heart.
For finishing: if there is no God, why are you too much worried about Him?
