There are two theories:
- the covid19 was created naturally and just happen to happen near the only place on Earth (or one out of two or three places?) that study covid19-style viruses;
- the covid19 was created in the lab and leaked outside because of negligence and/ or sloppy procedures.
Your choice which theory you believe. But a lot of powers in this world have vested interests to make you believe in “nothing to see here theory”.
