There is this thing called the Fermi Paradox
The
Fermi paradox, named after
Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for

There have been a lot of explainations put forward but the simplest one may be they all wiped themselves out. Perhaps because of over population, limited resources that cannot possibly support the number of people on the planet and the resultant fight for these resources. Sounds familiar ?

We need to reduce the popluation on earth by about 60% to have a chance of surviving - perhaps the next pandemic will sort it out. Something with the infection rate of Covis and the leathality of MERS or SARS ??
An interesting problem for the next couple of generations
