Think about the observations that scientists and other theorists have found. For example, discoveries in astronomy have shown beyond a reasonable doubt that the universe did, in fact, have a beginning. There was a single moment of creation.
Advances in molecular biology have revealed vast amounts of information encoded in each and every living cell, and molecular biologists have discovered thousands upon thousands of exquisitely designed machines at the molecular level. Information requires intelligence and design requires a designer. Furthermore, biochemists and mathematicians have calculated the odds against life arising from non-life naturally via unintelligent processes. The odds are astronomical. In fact, scientists aren't even sure if life could have evolved naturally via unintelligent processes. If life did not arise by chance, how did it arise?
Philosophers agree that a transcendent Law Giver is the only plausible explanation for an objective moral standard. So, ask yourself if you believe in right and wrong and then ask yourself why. Who gave you your conscience? Why does it exist?
Lastly, people of every race, creed, color, and culture, both men and women, young and old, wise and foolish, from the educated to the ignorant, claim to have personally experienced something of the supernatural. So what are we supposed to do with these prodigious accounts of divine healing, prophetic revelation, answered prayer, and other miraculous phenomena? Ignorance and imagination may have played a part to be sure, but is there something more?
