"Science measures that the universe is increasing. Logic tells us that the universe was smaller in the past. Science calculates that a some point the universe was a 'singularity'... a nothingness. Science believes in cause and effect. What cause formed the singularity and what cause exploded it? And where did all the material of the universe come from?"
I don't know. I think, "i don't know" is a better answer than "I do know," as long as we have no testable hypothesis.
