Biblical creationism as a natural/historical truth is not compatible with current scientific notions of historic fact. However, the ideas presented in the Christian creation story bear no incompatibility with science when interpreted as spiritual or philosophical rhetoric. Interpretation is key.
There is lots of evidence supporting creationism. The fact that it does not line up with macroevolution- an unproved theory does not define it as false, it lines up with geology, the fossil record, DNA research and many other things. You can't base its truth off of evolution, prove evolution first
Science develops to the point where we can completely understand the universe.
We create a program that accurately simulates a down-scaled version of the universe.
In such a world, are we not the "creators" of a new universe that is fully compatible with all scientific theories?
What constitutes 'creationism'? What evidence is there that the universe we observe was not created?
The theories that science is based on are just theories, which cannot be proven true. Thus, theories add an interesting alternative to a belief, while failing to disprove it.
