Assuming God has either access to more advanced technology than us or more advanced knowledge, why would that be unreasonable? Something that seems computationally complex now (like factoring primes) might be more manageable with more advanced knowledge/technology. Terraforming, bioengineering, factoring primes, etc. are within the realms of possibility for our civilization, so why not for a more advanced being?
