Science has never observed life naturally developing from non-life on its own, therefore, the scientific position would be to assume that it did not naturally happen on its own (This points to either an Initiator/God or to extraterrestrials seeding and engineering life on earth and beginning evolution).
Science is a process and method for obtaining information about the natural word. It cannot observe anything. Since you don't know what science is or how it works, any claims you make about it are drawn from a lack of knowledge and therefore useless.
