Best argument for the existence of God

Proposition

The best argument is the cosmological argument, because it does not lead to fear-based religion.

But the acknowledging of one God eternal, infinite, and omnipotent may more easily be derived from the desire men have to know the causes of natural bodies, and their several virtues and operations, than from the fear of what was to befall them in time to come. [ First Cause argument presented ]...and all this without thought of their fortune, the solicitude whereof both inclines to fear and hinders them from the search of the causes of other things; and thereby gives occasion of feigning of as many gods as there be men that feign them.

Hobbes, Lev XII 6
