Where did the universe come from? Atheistic origin science has no answer.

Wow, where to start....

Where did the universe come from? Atheistic origin science has no answer.

It's just science, not "atheistic". The age of the universe has nothing to do with a god, and there are plenty of Christians who believe in the age/origin of the universe as science says.

The current “theory” is that the universe came into being from some explosion called the Big Bang. The standard Big Bang theory does not match smoothness of the cosmic background radiation. So the theory of Inflation was added to the standard Big Bang. That is the latest conjecture of modern science.

CBMR was discovered because of the big bang, not in spite of it.
Inflation wasn't "added". Expansion is still occurring and at an ever increasing rate. Space itself is increasing, everything is moving away from everything.

Now there are many problems with this “answer” to the origin of the universe. If nothing existed before the Big Bang, then the Big Bang violates a number of principle and laws of science. It violates conservation of mass-energy. The energy went from nothing to all the energy of the universe. It violates cause and effect. Nothing never just explodes and becomes something. It violates all observations, since nothing never just explodes into something. It also does not explain the origin of the laws of nature or why there is even order in the universe.

No one says the universe came from nothing.

If something existed before the Big Bang, then the origin question is not answered at all. If the universe always existed, then the 2nd law of thermodynamics says that all order disappeared an infinite time ago. But that is not the case. Also there is still no explanation of the origin of the laws of nature or why there is even order in the universe.

How can all order disappear an infinite amount of time ago when the universe as we see it today has only been around for ~14by?
The singularity is what existed "before" the big bang. And "before" does not really work in this context since our known, singular dimension of time also began at the big bang. IE, for all practical purposes there is no such thing as "before" before the big bang. It's the same principle as saying that at true north there is no such direction as "north", no matter what direction you walk you can only go south.

Spacio-temporal reasoning and eternity are hard things to mingle.

Something can't have a temporal 'before' in terms of time whenever time didn't exist 'before' (as you say). The concept of eternity, requires that there is no 'beginning', only a constant 'being' - an everlasting 'present moment'.

It's really, really difficult to think about these things with our conscious focus only being able to consciously experience a now, as well. We can conceptualize futures and pasts but we're never really 'in them', we're only ever in the present.

Trying to put a place without time itself in my minds eye is pretty much impossible.
