God asked Job to answer the question "where wast thou", should Job have the "understanding". It doesn't take much "understanding at all " to say "that's easy, I wasn't born yet". My 4-yo grandaughter could do that without blinking an eye. Neither does the passage say that this even was "the creation". It says :
Job 38
4Where wast thou when I laid the foundations of the earth?
declare, if thou hast understanding.
5Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
6Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
7When the morning stars sang together, and all the sons of God shouted for joy?
Since the literal "earth" is a sphere with a spherical core and full of molten magma, it has no literal "cornerstone", so it must be referring to something else. I say that it is speaking of the "foundations"(which I assume to be the Gospel) being "fastened" on Christ, Christ is the "Cornerstone" and, from God's perspective, since He is eternal, timeless, the beginning and the ending, the Alpha and Omega, the great "I AM" and is already in the future, God has indeed already laid those foundations in Zion and Job, and at that very moment which Job heard God ask "where wast thou when I laid the foundations of the earth?" Job was
already there, one of those sons of God, shouting for joy. That is a fact. The reason Job did not have the "understanding" to decipher that mindblowing reality was because Brother Job did not have the completed Word of God like we do. Now, that makes my hair stand on end WAY yonder more than a silly mis-interpreted story about angels mating with women.
