4 logical arguments for the existence of God

There are 4 main logical arguments (aside from Biblical arguments) for the existence of God. Here's a brief summary of each.

1. Ontological argument

• God is the greatest conceivable being possible. It is then argued that to exist is greater than to not exist, and therefore the greatest conceivable being must exist. If God did not exist, then God would not be the greatest conceivable being, and that would contradict the very definition of God. I personally like the other arguments better.
  

2. Teleological argument

• This basically says "Dang, the universe has such an amazing design. There must be a Designer." For example, if the elements in our atmosphere were even a few percentage points different, most living things on earth would die. The odds of a single protein molecule forming by chance is 1 in 10²⁴³ (a 10 followed by 243 zeros). A single cell has millions of protein molecules.

3. Cosmological argument

• We don't get something from nothing. We have a universe. Therefore, something must have caused the universe to come into existence. That something is the un-caused (always existing) God. If you saw a watch on the floor, you would assume there was a watch-maker.
  

4. Moral argument

• Every culture in history has had some form of law. Everyone has a sense of right and wrong. Murder, lying & stealing are almost universally rejected. Where did this sense of right and wrong come from if not from a holy God.

Despite all of this, the Bible tells us that people will reject the clear knowledge of God and believe a lie instead (Romans 1:25).
