My case against Creationism and Infinite regression

[dyresand]

Why?  The universe is simply a changed form of what it was 'before' the Big Bang'.

So, you don't think that the beginning of space-time and all physical reality (including physical laws) could be characterized as a new system? Please also explain how the laws of physics stop working at Planck time (before you get back to the singularity) and how the First Law of Thermodynamics mysteriously is exempt and will continue on not just to the singularity, but through to the other side. 

In addition, please tell us what came 'before' the Big Bang that avoids the absurdity of a past infinite chain.

There was nothing before the big bang i wouldn't even all it that i would call it more of a expansion of space time from a singularity. To put it like so 
a pin point of infinitesimally small matter that contains the whole universe in moments starts to expand because of how unstable it is. Given that outside of
that point literally nothing exists no space time matter etc. First few phases of the universe nothing existed as it was too hot time passes you have your first
elements hydrogen and helium given a little more time you have the formation of stars. All the first law of thermodynamics talks about is conservation of energy, adapted for thermodynamic systems. So given that the universe is expanding therefor energy is being spread out evenly eventually that leads to heat death. 
And there is no other side as the universe will be gone not with a whimper but total darkness and there is no other side unless you are speaking of parallel universes there is no point in going to one.
