I believe in God, therefore a supernatural world. This belief is reasonable based on what I have observed. It follows logically that on omnipotent God could have created the world in 6 days.
This may appear to be an unreasonable belief to some who do not believe in God or a supernatural world. Therefore my question remains, is it unreasonable to believe in God?

That is incorrect. Evolution is not incompatible with divine intervention, just as it's clearly not incompatible with human intervention.

And in the process building in place evidence that it took, instead, many billions of years.

Depends on your beliefs. If you believe ina God who created a universe that appears to be self-sustaining and following fairly consistent principles, no, it's not unreasonable. If, however, you believe in a God that is contradicted by the clear evidence at hand, then, yes.
Belief in the supernatural is not unreasonable so long as that belief does not contradict the known facts of the natural world. You may believe in elves, if you so wish, but if you choose to believe that streetlights are elves, then you're unreasonable. Believign that a God created the universe in six days, plants ahead of the sun... that's unreasonable. Believing in a God that created the universe via more "natural" means, and explained it via parable to goat herders who woudl not understand thigns like evolution and proton decay... that's more reasonable.
