Thoughts that are not mine

I guess I don't understand what the paradox would be.

Perhaps I'm not understanding what you are proposing papercut, but to my understanding humans colonizing mars would have no impact on harvest or the incarnation of 3rd density souls. 3rd density beings will do as 3rd density beings will do. Even if earth's 3D cycle ends, it doesn't make a difference. The beings who are prolonging their lives via technology on Mars would simply be trapping themselves in their 3rd density bodies. If they have children then those bodies will be inhabited by beings needing 3rd density experience. There are always beings somewhere in the universe wanting a 3rd density incarnation, and they will readily leap into an available 3rd density bodily complex that formed whether it was on earth, or off of it. It is also possible that evolution of the biology will continue off the planet earth, meaning the offspring of these beings could potentially be hybrid 3rd/4th bodies and the next generation of offspring would lean even more towards 4th density physicality until in a couple generations, just as with earth, the bodies are no longer part of 3rd density physicality and reside solely in the spatial continua of 4th density itself.
