I think you're misusing the principle of observation as it pertains to science, Heywood. It doesn't mean you have to see the origin or the cause of a phenomenon. The observation is the identifying of the phenomenon's effect - "hey, that apple just fell to the ground" - which can then be investigated to determine the cause.
Does that cause necessarily suggest intelligence? Such may be revealed to be the case, but we have no justification for assuming that prima facie and subsequently disproving it. That would be absurd.
