The same notion is found in the initial conditions of Creation of the Universe of our existence. Before inlation of space and time, below planck length space and time the command ‘Light Be’ cannot happen, so God allows His created dimensions to manifest sufficient that electromagnetic energy/radiation can be. The God uses His creation to bring all the rst into being following set physical laws for the interactions of waves, etc. regardless of how long it all takes.
Here -- and in your #66 -- you're "preaching to the choir"...
You won't hear or read me saying that anything other than the inception of ex nihilo creation (from nothing -- to a singularity of energy, time, space, matter) occurred "instantly".
And, God, may not be "timeless", per se: He, Himself said that He spent six days in His own time to create and form ("develop" ) "all that is". And, then, He took a day of (His own) time off to rest. ...or so He said in Genesis..
