Come on guys. Isn't it obvious? The Coronavirus was brought to us by a multi-dimensional intergalactic race of beings known as the Tolatan (at least that is what they call themselves). They often appear to us in the form of a Sasquatch, or Bigfoot (Colloquially read: Samsquanch) because they believe this appearance will be odd enough to be notable but familiar enough to appear mostly un-threatening. After years of trying to communicate with us with large, deep "Woo Woo Woo" noises, which they initially believed was how we communicate, due to their only observations being from long range in lunar orbit, as most sound they pick up is the sound of an engine, such as helicopters and combines, they have become frustrated.
They introduced Coronavirus in order to reduce our population is size, primarily, for their inevitable attempted assimilation, or if necessary take over, but also to focus our attention on one issue and get rid of the many political distractions so that they can observe commonalities in our various languages and develop a better communication strategy after their on the ground observations confirmed that we actually communicate differently than they first estimated.
Keep your head buried in the sand for as long as you like. But when the Tolatan come, you'll all be sorry you didn't listen to me.
By the way we don't have all the facts to form a solid idea so of course it's all just conjecture on my part.
Time might reveal the bigger picture.
