Does the creative "spoken word" of Jesus (e.g. Luke 18:42) demand a Young Earth Fiat Creation interpretation of Gen. 1:1?

Since Jesus could *create* living organs (eyes, legs, whole bodied such as that of Lazarus, etc.) and even bring food into existence, in a split moment of time, do these feats demand accepting the short six days of Creation listed in Genesis 1 as FIAT CREATION, and not representing billions of years? Is this what the verses say? In response to God's (Jesus's) command did objects only have "To be" rather than "To become" during the creation week? It only took Jesus a nanosecond to speak and then produce healings, create fresh flesh (to the lepers) or reconstitute a decomposed body. - Be clean - Mt. 8:3 - Stretch out your hand - Mk. 2:5 - Receive your sight - Lu. 18:42 - Lazarus, come forth! - John 11:43 - Young man, I say to you, 'Get up' - Lu. 7:14 - He drove out spirits with a word - Mt. 8:16 - Just say the word and my servant will be healed. - Mt.8:8 Since it is the same Person in the first century as at Creation (John 1:1-4), do the bible verses in the N.T. and the O.T. demand a real week of time as we know it? Is this one of the major reasons Christian Young Earth Creationists accept a short time (not billions of years) for their interpretation of Genesis 1? Would they reason that it is stretched out to a 7 day week to give the man He was about to create an example of a salubrious work week? [Even though God (Jesus) could have done everything in a split second (or whatever a "second" is called in the frame of Eternity). Perhaps a note from the astronomer, Hugh Ross, would provide insight: according to modern astronomy, the mass of the universe (elements) were all created in one hundredth of a billionth of a trillionth of a trillionth of a second! This is the conclusion of modern science, not a concoction of theologians.
