The explanation of scientific reasons that maybe it was a lab leak

SARS epidemic At least five independent spill overs of the SARS virus into humans Live animal markets followed by human to human E.g. Guangdong Province, November 2002 to January 2003 SARS, later on in 2003 – 2004 Additional independent subsequent spill over infections in humans Civets identified within 6 months Early SARS viral samples from humans contained genetic mutations that reflected prior circulation and adaptation in palm civets In total contrast Chinese government, asserted that the COVID-19 originated from a natural zoonotic transmission occurring at the Huanan market Geo-temporal spread of COVID-19 in China, December 31, 2019 to February 11, 2020 Earliest identified SARS-CoV-2 well-adapted for human-to-human transmission Early SARS-CoV-2 variants had little genetic diversity, 2 nucleotides out of 29,900 (Adenine, Cytosine, Guanine, Uracil) No evidence of previous intermediate host circulation Genetic similarity between the environmental samples and human viral samples, supports the likelihood that the virus found at the Huanan Seafood Market was shed by humans
