Do you even know what the difference is between a theory and a law? They aren't even comparable - laws are the what; theories are the why.
As pointed out by others the amount of empirical evidence is huge for the big bag and age of the universe, including (but not limited to):
1) Elemental composition of the universe
2) Value of the Hubble constant
3) Cosmic microwave background
4) Age of the oldest detected astronomical features
How exactly does "the entropy of a closed system always increases" disprove this? Energy, in whatever form, is still energy. Be it matter, potential or kinetic (heat), or for that matter gravitational (i.e. the singularity before the big bang) its all still energy.
And the bible is. . .
How exactly is that the logical conclusion? You're saying that a simple theorem, which explains pretty much everything we see in the universe (i.e. the big bang) is LESS logical then a sheepherders myth from 3000+ years ago which is both selfcontradictory, but also contradictory to many things we observe in our universe?
Unusual logic.
