Or this is a deliberate attempt at deception by two nations (the two most powerful on the planet incidentally) who both have a lot to lose if the lab leak hypothesis were proven true.

Why am I always required to believe a conspiracy?

Reminds me of those kids who forget their lunch in their backpacks when the summer holiday starts and find it again 6 weeks later.

This is off topic, but: are your summer holidays really only 6 weeks long? Which country is that? (In Russia, where I went to school, it's almost always three whole months.)
