Bottom line: Alpha is Xi, Beta is Xi... Nu is Xi, Omicron is Xi... and Omega is Xi.
No because the Americans knew all about the weaponing of Coronavirus, we helped pay for it, and there is a report that an American contractor transported the closest virus in the wild (from Laos) to the Wuhan lab in early 2019 I am pretty sure. This is the same contractor who illegally funnelled money to the lab for the government, I cant recall the name.

That makes BANAL-52 more genetically similar to SARS-CoV-2 than any other known virus. Previously, the closest known relative to SARS-CoV-2 was RaTG13, which was found in horseshoe bats in 2013 and shares 96.1% of its genome with SARS-CoV-2, Nature News reported.
