There are four great questions that man tries to answer in life. These are called the great philosophical questions:
– Who am I?
– Where did I come from?
– Why am I here?
– Where am I going when I die
This question is no doubt the most important question in the universe. If God exists and the Bible is true, then we are in trouble! If God does not exist and there is no purpose to life, nor is there life after death, then we are in trouble! So this appears to be the ultimate question with crucial consequences.
If God created everything, then who created God?
God is either self-existing or self-created (http://www.ligonier.org/rym/broadcasts/audio/self-existence/)
Self-created = This causes a conflict and a contradiction. God will have to exist first to create himself.
Self-existing = He has always existed
