Firstly I would say believe in some thing otherwise you will end up believing in every thing, and only then ask or compare.

The three things I memntion above are:-

1. Ones Intilect
The way one thinks and ask the questions. For example who made this world how did this all started etc.
2. Second how you Feel. Your Heart
How you feel about it does believing in some thing give you peace at heart and make you happier?
3. Is your soul..Once that leaves you have no life..
Food for the soul is beleif. There is no doubt that every living thing will die. The question is what will happen to us when we die. What is the purpose of our creation.

Once you ask your self all the above question you start to think and that is the start of you belief in some thing.

Good Luck
