on one of the G+ communities i mostly lurk, but reply from time to time a peep posted a video clip which claimed to prove God without referring to the scriptures. basically the short version...someone made a cellphone, a plant is more complex then a cellphone therefore someone made the plant. it's an old argument from the 16th and 17th centuries..know as Deism, but that only gets you so far, in fact the Deists argued that God created the universe and walked away...and i'm sure the the ancient alien theorists would contend it was an alien presence in concert  with evolution,not God...the argument only gets you so far...peeps who believe in Theism not only believe in the creator God or gods, and that they are involved to a less or greater degree in universe and the people of the universe....
Christianity is monotheistic...one God who is both the creator and concerned about his people, but  you can only get to belief thru faith...not logic, not science, not empirical reasoning.
