Since God looks ahead, He probably spent quite a bit of "time" plannng this universe before He put it into place.
He would have had to conceive of the physical laws, decide what parameters He was going to use to plan it, right down to biological reactions, making some planets suitable for life, putting a planet with a moon to stablise it and provide a first stepping off point for the humans to start exploring space, decide when He was going to put in a personal appearance as a human being in the form of God the Son, work out how He would separate the goats from the sheep and keep them separated, plan how He would use the angelic beings while still allowing for their potential rebelllion.
Of course He started with nothing - just a plan. I've said this before but this universe appears to be a "sum zero energy universe" ie. it adds up to nothing. You might say it's nothing but a plan - a blueprint put into virtual reality (from God's point of view) until its time to present the real thing - the new heavens and the new earth.
Of as my old pastor put it, why would God give us humans a really solid universe considering our sinful nature - our endless wars, our cruelties, our pride, our endless violence and destruction?
He would have had a lot of planning to do, followed by maintaining this virtual universe until it had served its purpose.
Even a relatively minor event like healing the deaf man involves more than the simple statement about healing. He would have had to fix the root cause of his deafness, create neural pathways in his brain so he could understand the new sounds, give him enough language skills (possibly in four languages - Hebrew, Aramaic, Greek, Latin) so the deaf man could speak languages he'd never heard before, give him functioning vocal chords which had never been used with any degree of finesse after being mute, ensure his inner ears were working as they should, and do all this in the blink of an eye.

Sensitive structures
It's the amazing sensitivity of our ear structures that doom them to early decline, he says.
The softest sound we can hear corresponds to air vibration as small as one tenth the diameter of an atom. Our brain can automatically detect differences in sound on the order of 10 millionths of a second.
That's the detail God had to restore.
And plan before He created anything, along with all the other fnicky details.
