I thought it took a week for God to put it all together. Then the Jews wrote the history itemizing the birth from Adam on and his descendants along with their multi-centuries long lives. I saw a lot of detail there in Genesis. Most Biblical Scholars put the age of the Earth about six thousand years old. Just add the week of God's work to get the age of the universe. Not so silent to me. Of course, it is not congruent with geology, genetics, archeology, paleontology, and cosmology.
And, again, Genesis is silent about the physical age of the earth.
Look instead at what Genesis requires by the actual text.
Genesis 1 speaks of the earth bring in a condition which is entirely consistent with the idea of catastrophism. The word frequently translated as “create” is actually the word for “prepare”, to make something from ingredients already on hand.
That doesn’t mean the The Lord didn’t create the universe, only that it didn’t need to happen in the moments before He was hovering over the waters.
Genesis also requires that all the forms of life created during the time specified were created before the woman, not before the man because some exemplars are presented as being specially fashioned, rather than being called forth from the earth, after The Lord declares it is not good for man to be alone.
The time period indicated is then far too short to be discerned in the fossil record.
Just as a Genesis is silent on the physical age of creation it is likewise silent on what life may have existed before it was brought to the state mentioned in Genesis 1:1.
This is not that out there as we find references to both making things new and to official epochs reckoned to be distinct from each other in Scripture.
Genesis 1:1 might be thought of as the start of just those sorts of thing with just as much adherence to the actual text as YEC has ... therefore it is proper to describe YEC as a superfluity.
