You are correct, sir!
Take a course in Theology, it will actually blow your mind. It blew mine, and left me inspired by the authority. It will show God, by definition, is the creator of the whole universe, therefore he is the creator of time. So he's not limited by the time dimension that he created, so has no beginning in time God is the high and lofty One that inhabiteth eternity (Isaiah 57:15). Therefore He doesn't have a cause.
There's evidence that the universe had a beginning. This can be shown from the Laws of Thermodynamics, the most fundamental laws of the physical sciences.
The Bible states we don't use our whole brain, therefore we cannot understand the answers to our questions on how it all happened even when explained. God promises that one day we will understand, because he will give us the gift of using our whole brain. The fact that everthing is perfectly in place for our purpose here on earth is on example of evidence (for me) to believe that there is indeed a powerful force behind it, There's many religions, many that believe different from each other, but all of them believe in divine power.
