If you say it, I doubt it.
Anyone who knows how can analyze it. All of the genomics analysis tools are publicly accessible. You can do it yourself.
First, the virus genome sequence: Severe acute respiratory syndrome coronavirus 2 isolate Wuhan-Hu-1, complete genome.
Next, the sequence analysis tools: Basic Local Alignment Search Tool. The most pertinent tool here is the "VecScreen" tool; since a vector is used for genetic engineering, you would find it if present in the SARS-CoV-2 genome.
Finally, the tool that molecular biologists use to compare sequences from different organisms: Multiple Sequence Alignment. (Note: this tool is being retired at the end of January, but the new tool is not available yet.)
If I am lying about doing the sequence analyses which show that the SARS-CoV-2 is a natural virus, then you should be able to do the same analysis and show exactly where the signs of genetic engineering are and demonstrate that I am lying. I've provided almost everything you need. What I did not provide was links to other coronavirus sequences for the Clustal analysis, but--since you apparently know more about molecular biology than I do--it should be trivial for you to find them.
