Science recognizes gravity is a force. Of course the force itself is unfalsifiable. It is a given. It is not tangible either. That is to say only its effect is manifest to the senses, not its essence. Does that make it by its very nature an "unscientific" object for consideration? No. Science draws inferences from, and describes in much detail, this force by observing its effects.
There is no reason science cannot address or consider the factors or forces that cause matter to become and remain organized while behaving under predictable laws by using a model of intelligent design, for just as the force of gravity cannot be falsified but inferred, so can the operation of an intelligent agent not be falsified but inferred.
Denying intelligent design where matter is organized is like denying the force of gravity when objects are attracted to one another by mass.
This is exactly what science does. Haven't you been paying attention?
You might give some thought to your phrase "predictable laws."
