What do you mean by "outdated"? Scientific theories don't go off with age, they depend on evidence and the scientific evidence continues to point to evolution as the best theory. Modern biology might be more advanced than it was in Darwin's day but nothing's disproved the fundamental ideas. That's like saying that the discovery of the Higgs boson makes the Earth orbiting the Sun obsolete.

And as for your second point, it's true. God could use evolution as a tool. God could hide fossils as a joke. God could just be having fun by letting us build up our quaint little theory of evolution before suddenly dumping a herd of unicorns in the savannah. God could, if he existed, do pretty much anything for any reason completely incomprehensible to us. And that's precisely where creationism falls down as a scientific theory - any flaw is just covered by "maybe God did it just because" and it can't be disproved.
