Have you ever studied how a mass of hot Lava can rise up in the middle of the Ocean and in a few years it has life growing on it? The wind carries Life to it and Algae from the Ocean clings to it and grows. Life is the most resilient force in the universe.
Now consider these possibilities
1) If we are constantly being bombarded by Meteors, why couldn't some of them carry life from some distant origin? That Life then grew from simple Amino Acids to form complex organisms
2) If you understand the Electromagnetic Spectrum you will know that Light is merely a small fraction of it. Matter can form from abstract sources. In Dohgon Spirituality we call it a permutation process. In Science they are known as Quarks. What if an advanced race of beings who understand how to transport complex information (DNA) through Light were to send Life out into the Galaxy in hopes that it may find a suitable place to germinate and grow?
Dohgon Spirituality says that Life is the result of an intelligence(Dark Energy) that does not exist in this dimension. Matter along with Life is just an exercise in the ability of that Dark Energy to exist outside of itself. When we gain a better understanding of Black Holes we will understand the origin of Life.
I would much rather believe in that than in a story of some bored beings who decide to create humans in their own image then begin to fight over who will control us. If God is all powerful then creating descent in his beings is merely for his amusement. It comforts our ignorance though which is quite satisfactory for some.
