Assuming young-earth creationism, could Adam calculate the age of the earth using science?

I some times wonder when God made the garden, to beautify it, the trees for example must have been differing height and width.  Therefore, assuming a literal 7 day creation, if Adam were to cut a tree, the day after he was created, would he have found thick trees with several rings?  Would Adam really be able to determine how old the world was studying rocks, trees, etc.? Was science prevented from ever understanding creation by virtue of its incomprehensible design on day one? Would a rock's radioactive print seem like a billions years old, when only one day old? How would a fully created universe seem like a day old? Would not some things appear to have started motion long ago to reach the place where they were created? That is a lot of questions but it is really one: 'Could Adam calculate the age of the earth using science?'
