The rest is up to the accumulation to absorb enough moisture to start some growth. The possibility for life is given to each form of block and fruitfulness is allowed. That is the process of the rock building essence. In creation one thing is certain that life can grow on any part if moisture is added and life is allowed. Creation builds for life, and not only as an ornament of existence.
Sustained life is another point, though.
It will be a fact when the blessing of the Spirit is set upon the rocks. In that movement all life has ingredients to come to term with growth and its ability to familiarize itself to produce growth for the future. In retrospect we can say now that there is no rock without life. All has existence heaped upon existence, and the blessings of life are stored and entered as an accomplishment. We come to Earth in a moment.
