The virus is over 96% from the disease reservoir known as the Horseshoe Bat. Why go to the time and trouble of making it in a lab, when it can be found in this bat? Similarly, why would anyone plant explosives in the twin towers when they were going to fly planes into them.

'' In 2019, a coronavirus pandemic began in Wuhan, China. Researchers determined that the coronavirus is likely closely related to those found in horseshoe bats.''

Increasing evidences demonstrate the link between the 2019-nCoV and other similar known coronaviruses (CoV)
circulating in bats, and more specifically those of the Rhinolophus bat sub-species. These sub-species are abundant
and widely present in Southern China, and across Asia, the Middle East, Africa and Europe. Recent studies indicate
that more than 500 CoVs have been identified in bats in China. To be noted that serological studies conducted in
rural population living close to bats natural habitat in caves revealed a 2.9% bat-CoV seroprevalence, demonstrating
that humans exposure to bat-CoVs might be common.

However, the route of transmission to humans at the start of this event remains unclear. Bats are rare in markets in
China but hunted and sold directly to restaurants for food.
2 The current most likely hypothesis is that an
intermediary host animal has played a role in the transmission. ''
