Given the fact that the man codified an immutable law, such as the Law of Biogenesis
Immutable? Really? So might I ask your definition of "life" here? And let's make sure we really can classify everything into "non-life" and "life", given that an "immutable" barrier separates the two.
But again, this fails to address the fact that for anything at all to exist, whether it be subatomic particles, a compound chemical "soup," or energy, was still required of something, at some point, to be eternal.
No it does not, not in the limited sense of eternal you are using. But then again, it is quite possible that the universe is eternal (in your sense), so it does not matter either way.
God can create an eternal universe and he can create a non-eternal universe (as far as we are aware). An eternal universe can exist without God and so can a non-eternal universe (as far as we are aware).
