We humans have brains that make us selfish. Our most popular worry is about our own end of life. Religions, including Christianity, talk of ways to extend our lives forever. A less selfish preoccupation would be extending the life of humans on the planet.
There is universal agreement the sun is burning itself up. All the praying in the world will not stop humans from being vaporized.
Other problems that could accelerate something close to end times includes climate change. We can’t seem to recognize living a little differently could reduce the odds of a catastrophic impact on future humans. When our brains are full of our mortality it is hard to change course.
A problem, maybe one closer in time, is reversal of the polar magnetic fields. Inside the magnetic field that pulls our compasses to approximately 360 degrees (293 in Midwest) are explosions and change. Only 800,000 years ago, 600,000 before humans, the poles reversed. They almost reversed 40,000 years ago. Scientists say they cannot predict when compasses will point south but at some point they will.
The magnetic field protects us from solar rays. A polar reversal would mean thousands of years of exposure to these rays for a good portion of the earth, eliminating most life there. Also, unprepared satellites would go out of service.
We all know that satellites now determine our health and safety. There is little or no redundancy for functioning without them.
In my view, preparing for pole reversal is more important than preparing imaginary souls for imaginary afterlives.
