"Until just a couple of hundred years ago, most people thought that a god or gods controlled everything. Why did the wind blow? Why was there lightning and thunder? Why did the sun, moon, and stars apparently go around the Earth? Why did someone get sick and die? Why did anything happen? Well, obviously, God did it. If a person doesn’t know how something works or why something happened, they can say, “God did it.” This is known as the “god of the gaps,” or the “argument from ignorance,” and it is at the heart of the conflict between science and religion. Science looks for natural causes, while religion looks for supernatural causes. Science is steadily winning, because as we understand more and more about the universe, the gap where God might function grows smaller and smaller. Every time we learn more, God has less room to operate. When we learned what caused the sun to apparently move across the sky, there was no need for the Greek god Helios and his chariot. When we understood what caused lightning, there was no need for the Greek god Zeus, the Roman god Jupiter, or the Norse god Thor.
In fact, the understanding of lightning was one of the first areas of battle between science and Christianity. When Ben Franklin discovered that lightning was just a big electric spark, he invented the lightning rod. It was enormously successful at preventing buildings from being struck by lightning. However, this caused a bit of a conundrum for the church leaders; should they trust in their god to prevent lightning strikes on their churches, or should they use these new lightning rods? Up until then, lightning hit churches much more frequently than other, more “deserving” buildings — such as taverns or houses of ill repute. “Why was that?” they might have wondered. Could it be that churches had spires and were taller, or was it SATAN and his WITCHES? …… Actually, that is what they often believed, and many a supposed witch was executed for having caused the destruction of a church. When they started putting lightning rods on churches, witch killings stopped soon thereafter. However, the obvious fact is that they were putting their trust in science and lightning rods, not religion and prayer."
