SARS-CoV-2 exists, beta coronaviruses exist, so do alpha gamma and delta. People that claim it never existed are fucking morons. Sorry champ. Omicron has mutated extremely far from the Wuhan strain, and the latest mutant offshoots of Omicron have mutated equally as much again. The mutations are mostly in the spike S1 and S2 but also other genes as well. People claiming no one has seen the virus obviously haven’t seen the Electron microscopy pictures, hence are ignorant and know not what they speak of.
