What if you find a watch in the middle of the desert?
What would you conclude? Would you think that someone dropped the watch? Or would you suppose that the watch came by itself?
Of course no sane person would say that the watch just happened to emerge from the sand.
All the intricate working parts could not simply develop from the metals that lay buried in the earth. The watch must have a manufacturer.
Blind chance cannot produce a working watch.
But what else tells accurate time? Consider the sunrise and sunset.
The timing of the Sunset and Sunrise are so regulated that on any given day of the year, the Sun will rise and set on the exact time it did on the same day the previous year.
And it will be just like this in the following year and the years to come.
But who regulates the timings of sunrise and sunset? If a watch can not work without an intelligent maker, how can the sun appear to rise and set with such clockwork regularity? Could this occur by itself?
Ofcourse not. There is a Creator who designed the sunset and sunrise. There are people who deny the existence of such a Creator.
What would they think if they found a watch in the desert? An accurate, working watch? A beautifully designed watch? Would they not conclude that there does exist a watchmaker? An intelligent watchmaker? One who appreciates beauty? Such is God who made us.
