According to Leonard Susskind[1], fine tuning is a compelling argument by itself[2], and the strongest case is the cosmological constant.[3] In a nutshell it is a sort of repelling force first proposed by Einstein to create a workable model for a static universe who later regretted it as one of the biggest mistakes in his career. However, the theory is now back with Nobel prize winning research showing that expansion is accelerating, which would require a positive number. It could explain a large portion of "dark matter."

When expressed in one way, it is 10^-122 "units of the square Planck length". I'm not smart enough to completely understand it, but it is (according to physicists) an incredibly precise ingredient in the various properties of physics that make our Universe possible. Any larger or smaller and the model falls apart. If it is an accident, that is one hell of a lottery ticket.
