What is the creation science theory of the origin of light?

If i can plant a seed that 300 years later would be 100 meters high and contain millions of life forms and become home to the birds that roost in its branches, why cant God of created the whole universe simply by planting a seed that has grown into a cosmic tree and now has life roosting in its branches? Obviously i say this using the parable of the mustard seed as reference.

Well a seed for example will be subject to the laws of quantum mechanics and once it has germinated relativity, even plant cells have action potentials that will release photons. So even though it is a universe away from being a universe a tree actually makes a good analogy for a big bang universe. And it certainly has the potential for photon production, slight i know but the universe has more dark places than lit places.As for Jesus and God, its a personal experience thing, nothing makes more perfect sense to me than for me and the universe to belong to them. By believing in God and Jesus then obviously i know they must know everything there is to know about everything so i can read into it what i want as long as my heart remains faithful then my mind wont poison the truth.
I cant think of a better analogy for the universe than the parable of the mustard seed (in laymen's terms of course). And you cant get any nearer the cosmological truth about our material destiny than "you came from the dust and to the dust you shall return"
May i ask what your beliefs are as regards your existence?
