U.S Covid enquiry

[jon1959]

I read something to the contrary today, concerning the long term effects of Covid. Apparently it's more likely than not to have been engineered. Also the US Govt. has just published their findings after a 2 year study into Covid and say it almost certainly came from a laboratory leak - which was pretty obvious all along but no Govt. would admit it..

Why was it ‘pretty obvious’ that ‘it almost certainly came from a laboratory leak’?

I understand that was a serious hypothesis. I understand you wanted that to be true. But beyond that, why was it obvious?

Lab leaks were not the likely cause of previous virus pandemics were they?
