5 Basic Proofs of Christianity
1) Universe can't cause itself since everything in nature has a cause, and the universe can't always have been existing due to the exponential progression of conscience for we would not still be sinning to the extent we still do.
2) The complexity, intricacy and fine tuning of the universe proves there is a Designer.
3) Without God there is no moral objectivity.
4) The multiple eyewitness accounts of the resurrection of Jesus in various group settings under different circumstances and different classes of people.
5) Personally experiencing God in your life.
