It cannot be a young earth. Not going into methods of dating and just using the biblical 'note' of 'in the beginning', I am suggesting that this earth is very old. Much older than we have ways of measuring at this moment of knowledge. Created dark and filled with water, it may have been left to its own devices (with all the information necessary) to emerge as we know it today, or moved upon at a later time to give it a more pleasant look and to support the addition of all life.
