Our magnetic field protects us from blasts of solar radiation & likely existed soon after the planet formed. This may explain why Earth is habitable & Mars is not. Without our magnetic field, solar winds would strip away Earth's atmosphere & oceans.

'Magnetic' Discovery May Reveal Why Earth Supports Life and Mars Doesn't

Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, may be 750 million years older than scientists had previously thought.
