My point is that if scientifically ALL possibilities must be looked at.
Not even close. Not how science works. Before you jump into biology, take a class on basic scientific education first. Your grasp of science is woefully lacking.
In order to look at all possibilities, you must consider an infinite number of combinations, for instance, that a rhino made of pigs is responsible for creation, or that drywall spackle is, or that life sprang from nothing with no cause, or that life came from a collision of an ice cream truck and a comet while having lunch in the core of a neutron star.
