Gottfriend Wilhelm Frederick von Leibniz (1646-1716) was a German philosopher and prodigious scholar. He invented the infinitesimal calculus independent of Newton. Today we still use his notation. He invented the binary system which makes possible all modern computer code. He designed the first purpose built library. He organised the mining of the material for the linseed oil lamps that would line the streets of Venice. Plus much more info here at wikipedia.
The first question which should rightly be asked is this: why is there something rather than nothing?
Based on that question he formulated the following argument for God’s existence from the principle of Sufficient Reason.
1) Everything that exists has an explanation of its existence, either by necessity of its own nature of by an external cause.
2) If the universe has an explanation of its existence, that explanation is God.
3) The universe exists
4) Therefore, the universe has an explanation for its existence
5) Therefore, the explanation for the existence of the universe is God.
Instead of defending it myself I’ll just point you to a video of Dr. William Lane Craig presenting at the Philosophy department of Wake Forest University in North Carolina the annual Carswell Lecture for 2008.
Here is the full video.
