Yawn. Mars had life it went whoosh. Hypothesize how. It losing its magnetic field was caused by what catalyst. What catalyst. An Impact. Or solar burst. Its surface water has evaporated, its biomass has disintegrated. Explained by its atmosphere igniting. The same affect. It would displace its magnetic field as well as turning the planet into dust with traces of carbon or subsurface frozen water. Simple conflagration.

We could also become Mars.
