Hmmm... lots of misconceptions about science in the OP.
Firstly, nothing in science is "provable". There's no such thing as proof in science because science is only capable of
disproving hypotheses. Thus, only disproof exists in science; proof does not. We accept an hypothesis only on the basis that it has not yet been disproved by the evidence (that is, it is supported by the evidence).
Creation cannot be proved
1. It is impossible to devise a scientific experiment to describe or replicate the creation process.
I guess that depends on what you mean by "creation". If you mean magically poofing something into existence from nothing, then yes, I agree that creation is not possible to test because science does not have the ability to falsify magical scenarios. I guess I would question whether this is truly a biblical definition of creation, though.
2. Creation is not taking place now; therefore it was accomplished sometime in the past, if at all, and thus cannot be observed or tested.
How do we know that creation is not taking place now? Are people not being born every day? Are we not each individually a creation of God? Are new species not evolving in nature?
1. If evolution is taking place today, it operates too slowly to be measurable (on the macro scale), and therefore, is outside the realm of empirical science.
What do you mean by "macro scale"? Scientists define macroevolution as the process of speciation, which is indeed observable and has been observed in real time. If you mean evolution at even higher levels (Linnaean ranks), then you're right, we cannot observe that in real time (higher ranks are only recognizable in retrospect). That doesn't make the concept of macroevolution non-scientific, though. For something to be scientific, it must make falsifiable predictions, which macroevolutionary scenarios certainly do. For example, they make falsifiable predictions about the pattern and order of the fossil record, which can be observed.
