Philosophically, it seems very reasonable to me that a Creator of the universe must exist. Here's why.
1. Something exists.
2. Nothing does not produce something.
3. Something must have always existed.
4. The universe has not always existed.
The background radiation echo, the motion of the galaxies and the second law of thermodynamics all point to the fact that the universe began to exist at a finite point in time.
5. Therefore there must be an eternal power beyond the uinverse that caused the universe to come into existence.
If you were a skeptic, or are a skeptic, how might you seek to refute this line of reasoning? I'd be interested to hear. For more on God's existence see my study here.
