I just see a different reality than you see. The virus spreads to everyone all at once, the hospitals get glutted for a week or two, then it is over, so yeah, the numbers plummet; not because of social distancing but because nothing stops a virus, so the virus attacked the people most vulnerable to it, they got sick, the numbers spiked, then the numbers plummet .... because everyone who was going to get sick, got sick. It is that simple. The social distancing did nothing. Look at Brazil and Sweden... no lockdown, the same spread rate as nations that did the lockdown, that's the normal spread rate for a virus; FAST. Viruses spread fast and this virus was even faster than most. So, you get spikes from that. The fact that we got hot spots (spikes) tells you that the virus spread fast, and it tells you that social distancing didn't slow it down, because if social distancing did slow it down, we would not have gotten the spikes.
A virus is a messenger RNA wrapped in a protein... AKA genetics. So, what they are doing in the labs is taking a coronavirus from a mammal and genetically engineering it to attach to humans. In the case of COVID19, they targeted the DNA in black people. That is the only thing that contained this virus; it was engineered to go after 10% of the population. If the mad scientists ever want to wipe out all of mankind, you would discover just how ineffective social distancing really is.
