I would disagree, all the evidence we have right now supporting zoonosis is circumstantial. The evidence being a mapping of early cases to around the market but given the shortcomings of this early evidence it's hard to rule out sampling bias: https://www.washingtonpost.com/documents/a5102da1-9b47-4e11-...
But so far we have not found an intermediate host nor any closely related viruses in any animals yet. By contrast for the two previous spillovers SARS and MERS they not only identified an intermediate host, but they have found many closely related viruses in animals due to the fact the virus is circulating and thus branching off into many variants. Just take a look at the phylogenetic trees of MERS: https://virologyj.biomedcentral.com/articles/10.1186/s12985-... and SARS-CoV-1: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1212604/
Plus Python is not suited for event driven systems.
Which would be shocking given that highly infectious viruses do not simply just disappear after a cross species spillover. Did covid stop spreading amongst humans when dogs/deer/cats got infected? Not only should an independent ancestor branch still be circulating but it should be circulating amongst intermediate species all throughout Asia. It's like a virus pre-adapted towards humans magically appeared and then vanished without a trace, I heard on virologist coin it as the "immaculate infection"
So why continue to fund such dangerous research if the research will be hidden when we actually need it?
One thing I am sure of is that life is not as delicate or requires such specific conditions to thrive. Only liquid water.
The Google search algorithm from 5 years ago was amazing, why they decided to change it for the worse is something I will never understand! And no I do not blame SEO entirely since that existed 5 years ago, what I am often looking for but can no longer find is information that has nothing to do with any products. It's not ads that I need to page through, but unrelated and bad results that are limited. I do not want to see the same results from page 1 on page 3.
Also I would like to point out that the vast majority of planets we detect happen to be around red dwarf planets since we need 3 transits for a positive detection which would require years for larger stars. Additionally to do atmospheric spectroscopy the solar system needs to be within a perpendicular line-of-sight of our solar system.
So keep in mind the planets/solar systems we are studying do not represent the typical solar systems around exo K/G type stars.
That is not true the composition and material of our solar system are the result of a Supernova remnants. The element composition of each nebula is unique since no star is exactly the same(although it could be quite similar), but outside of the other stars that formed alongside our sun 4.5 billion years ago, other solar systems have different element and isotope ratios.
Which is strange for a virus as you stated. "found to have jumped to quite a few other animals; cats, dogs, hippos, anteaters, manatees; it's clearly not picky". So why is it so hard to find the virus that spilled over into humans, this virus would have been better adapted towards their own species and would have not been replaced by the human variants. We find SARS circulating in animals all the time, but they all descend from the human variant.
It is the Immaculate Infection!
Almost all of the researchers throwing ad hominems at scientists who support a lab origin are NOT that lauded. Most had very low H-index scores prior to the pandemic. Especially Angela Rasmussen from the University of Saskatchewan.
