Is the Bible True?, page-457

Analogous to: "Killing Infidels used to be is acceptable. It is no longer acceptable to do this.

Sorry that I have to tell you this: the source of a great deal of tension is that some still think that it is not only acceptable to kill infidels but it is done by the will of some God. Why do you think they cry out "allahu akbar" when carrying out these deeds?

There. I told you that we would find a topic to fight about debate.

In the case of the earth's magnetic field, it was deemed to exist when it was detected - that's science.
God, evil spirits, good spirits, angels etc are deemed to exist even though they are only deemed to exist through faith - that's religion.

Discovery of the Earth’s magnetic field

Extract:
The tendency of a magnet to align itself in a north-south direction, so giving a magnetic compass, was discovered by the Chinese about 2000 years ago. Some hundreds of years later, they discovered that magnetic North, to which a compass points, did not necessarily coincide with true North. The horizontal angle between them is known as the declination, and the Chinese also discovered that this angle varied with time.

The magnetic compass arrived in Europe during the twelfth century, and proved a valuable aid to ocean navigation. By the sixteenth century the declination was being measured at various places so compass directions could be corrected for more accurate navigation. Also in this century, Georg Hartmann and Robert Norman independently discovered magnetic inclination, the angle between the magnetic field and the horizontal. Then in 1600 William Gilbert published De Magnete, in which he concluded that the earth behaved as a giant magnet.
