Alien Life Breakthrough

Science says nope.

I'm not sure how this one passed me by, but last month NASA released the findings of the most compelling evidence yet that there was once life on Mars after Perserverance analysed some "leopard spot" samples from an ancient riverbed.

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken

Now, we've all heard this many....many.... times before and they always end up being explained away by other non-biogenic processess, but the vibe around this one is seemingly different, with no obvious or easily explanable abiotic reasons.

Matt from PBS Spacetime has done a good video on it

I really don't think it's that unlikely.

You have to realise the timescales involved are almost incomprehensible to most people (myself including) the atmosphere and make up of mars was very different a long, long time ago.

If you think of "life" like a disease that can spread easily if the habitat can support.

It wouldn't be hard if were carried around in asteroids etc.

I hope it is life as unless they can prove the theory that a chunk of Mars hit us, Panspermia, transferring life to the Earth, it's evidence towards the likely hood that other life, not necessarily intelligent life, exists out there in the universe.

No, most of us I expect don't think 'life' in it's basic form is that unlikely, probably quite ubiquitous, but there's a difference between thinking/beleiving it and having actual proof!

The interesting part of the above video as well is talking about if life does turn out to be common, it then moves to the next question about why aren't we seeing any evidence of advanced technological life and the debate about The Great Filter and whether we as a species have that barrier still to cross.

Hence the seemingly prophetic title of the video about it being a portent of doom!

Haven’t been on the forum for ages and thought I’d missed the big That Jekka Gal outing/banning. Can’t decide if relieved or disappointed.

I think the world has come to expect life to be reasonably common in throughout the universe. It would be front page news to discover it, though.
The real killer would be an advanced alien civilisation.
