This is an old argument against determinism - I think a serious challenge is that:
1. Modern physics suggests you can implement such a lookup table for any subset of our universe.
2. We are a subset of the universe.
3. Therefore we are representable by lookup tables too.
...so your argument appears to prove too much, namely that humans aren't thinking beings either. Which is fine, but personally I don't think that's a useful definition of "thinking".
