Possible hints of life found on distant planet - how excited should we be? https://www.space.com/possible-hints-of-life-exoplanet-expert-voices-conversation

"
Now we have reports that JWST has identified carbon dioxide, methane and – possibly – the compound dimethyl sulfide (DMS) in the atmosphere.
The tentative detection of DMS is significant because it is only produced on Earth by algae.
We currently know of no way it can be naturally produced without a life-form.

On the really slim 1 in 10^50 chance they could ever visit a place like tha= >t, they would end up bringing back something that could wipe out all living=
creatures. Distance is a good quarantine.
