Archons "nuking" this earth in the far far future wouldn´t mean the end of the human biological body type, as they see this organic construct as best loosh producing vessel in this planet. They would probably just do that to push the future civilizations to go underground (at least in this timeline i´m in) I´ve read enough on warring alien factions (these so called aliens are most likely hyperdimentional beings just using a biotechnological body suits to navigate in this physical universe) to know that there is really something going on about this issue (UFO sightings are on the increase again) The hybridization program (the negative version by the grey and reptilians) could serve several purpose, one to make better vessels to create loosh (fine-tuning, which is why some are generational abductions) or to create body types able to survive other planets (prison planets) By the way, you got some valid points there, but lets see where all this goes over time, your take on this is as good as mine..
