There are a number of explanations of what is going on. I will list them first and then go into further detail. They are not mutually exclusive:
There is a pandemic caused by a virus
There is no virus and there is no pandemic
There is a plandemic
We are subjects of corporatocracy gone overboard (big business with no soul)
The elites or Powers that Be (PTB) want to depopulate the world:
To reduce the rate at which resources are consumed
To reduce the draw on public funds by people who are no longer productive
To prevent the chaos that would ensue if the current population overwhelms the ability to provide enough energy/food for it to survive
The PTB want to enroll us all into a social credit system and/or microchip us all (surveillance/control)
The PTB and particularly the (World Economic Forum) WEF want to rise above nations and implement The Great Reset, in effect creating a one world government without being subject to voters by virtue of their economic power
Implementation of the Fourth Industrial Revolution
The first was using water and steam to mechanize production
The second used electric power to create mass production
The third used electronics and information technology (IT) to automate production
A fusion of technologies that is blurring the lines between the physical, digital and biological spheres
One or more groups wants to conduct genetic experiments and/or fully launch a Transhumanist movement
Lockdowns are a political measure, quarantines are a medical measure
Aliens (comedy relief, but maybe not?)
Questions
Does an mRNA injection causes changes in the recipient’s DNA?
What are the Five Eyes and how do they fit into this story?
The Depopulation Agenda
Are more people dying than in previous years? This question is discussed by Maria Romana on her substack
Are fewer people being born than in previous years?
Are there more miscarriages than in previous years?
How has fertility been affected?
Birth rates in developed nations are already below replacement value. There are folks who are calling for more people, not less. Elon Musk in this video about what he describes as the upcoming population collapse is one example
Evidence for a Plandemic
No Need for a Smoking Gun a post by the The Aging Viking on Substack which describes how the development of the mRNA vaccine was accelerated
