People you all believe every thing have a source or origin to come this earth&universe?

every thing have a source or origin. its what we call secrets of the universe.i belief science every one can explain visible or invisible forces activities top to bottom. but no one can tell the source or origin.i can explain about Darwin theory but no answer for first form of human,bird,animal.i know solar activity minimum and maximum scientifically.no one knows who start and performed this activity.with out source nothing is possible.every thing cant perform them selves(ozone layer well planned activity.)need a source or origin for every perform activities.all incidents are not a coincidence.
