Earth’s Magnetic Field has survived…somehow…Mars’ Magnetic Field…SWITCHED OFF??
“Earth’s magnetic field is running down, so it could not have been going on more than a few thousand years, despite swapping direction many times. Evolutionary theories are unable to explain how this magnetism could sustain itself for billions of years. A young age for Earth fits the data best. See The earth’s magnetic field: evidence that the earth is young.
To explain the origin of a planet’s magnetic field, evolutionists invoke a dynamo effect produced by ‘movement’ of a liquid iron planetary core. However, with Mars, evolutionists have to explain not only the origin of a magnetic shield for when it was allegedly life-friendly, but also the subsequent loss of the shield now that it is hugely hostile to life. Here is how Cox does this:
“Just like Earth, ancient Mars was also shielded from the Sun. But between 3.5 and 4 billion years ago, Mars’ dynamo switched off. The aurora surrounding the [Mars’] poles slowly faded away as the magnetic field diminished, allowing the atmosphere to be stripped away by the solar wind. Without protection, sea evaporated, the surface froze, and Mars was transformed.”
Quite a story! But that’s all it is—a story to avoid invoking the Creator. A much more plausible account, at least for Christians, is that God designed Earth to have a magnetic field in order to protect life on Earth. Mars does not appear to have been designed for life, and hence does not need a magnetic field like Earth’s.”
