Ford trucks are built tough says the commercial and we can understand what the Ford motor company is saying. But what would you do if you met someone who said that Ford trucks have no creator? That person simply believes the trucks came from nothing. What would you say to prove him wrong? Do you believe the design features of the truck show evidence of a creator? What about the airbag? Tilt steering? AM/FM stereo? etc? The truth is yes, all these functions are the work of a mind that put them into motion, they have a creator.
Now what about a more sophisticated thing like a human being? King David took one look at himself and declared "I am fearfully and wonderfully made". Psa 139.14. Gen 2.7. David didn't have the knowledge of the human body like we do today, yet he knew that the body was the most complex working function on earth. So why do we have atheist's and skeptic's? If we can see a creator in the design of other things, why not in the creation of man? To question the existence of God is to close ones eyes to the work of his hands which can be clearly seen. Rom 1.19-22. Psa 14.1. 19.1-4. 102.24-28. 104.1-5. And for a bonus, the next time you see a rainbow remember God said such would be a sign that he won't destroy the earth by a flood. Gen 9.8-17
