There’s certainly plenty of intellectual hot air to go around.

They’re busy chasing government grants.

We should try Alpha Centuri. it’s only 4.35 ly away.

The atmosphere is thin and escapes continually, it might be possible all of it just drifted off into space...

I guess

No amount of evidence against life on Mars will deter NASA from spending billions of dollars and some number of lives to continue the search.

Clearly, the Martians need to promptly enact Cap and Trade if they are to survive.

I know for a fact that Martians only fart once a year.

Life on other planets is the secular humanists' substitute for God. It's an article of their faith that it must be there, whether they have any evidence for it or not.

NASA makes more money by looking for life and then still more money by discrediting all evidence that life exists beyond Earth. One would not like to disturb the paradigm.

Armed with the belief that life came into existence on its own here on earth then it must’ve came into existence everywhere OR maybe life on earth came from Mars.

Evidence? That’s on Mars!

I have $100 that says we will find at least microbes on Mars. Any takers? I have made this bet with several people here on FR.

There is already a lot of evidence that there is life on Mars, e.g., rocks that turn green (lichens?) in Summer and brown in Winter. The Allen Hills meteorite had clear evidence, i.e., nanofossils, in its interior. Those nanofossils are almost identical to certain Earth microbes.

BTW, how is this a religious issue? There are a lot of things in science that are not addressed in the Bible.

I didn't think that was clear at all. I wouldn't be surprised if they find microbes on Mars but I wouldn't want to lose $100 by betting on this meteorite.

Which will have arrived there on a meteorite from Earth.

The "clear evidence" claim for fossils in the Allen Hills meteorite was debunked years ago.

"The new paper reports that magnetite, an iron-bearing mineral found in Martian meteorite ALH84001, was likely caused by inorganic processes, and that those same processes can be recreated in the laboratory, forming magnetite identical to that found in the Mars meteorite."

I saw the meteorite and examined the photos at Johnson Space Center where I met the researchers. Someone may think they have “debunked” the observations. However, the nanofossils have a distinctive shape as well as the magnetite signature.

If you are 100% sure that life will not be found on Mars, then take my bet.

You saw magnetite, which your blind faith transformed into fossils in your own mind.

I debunked that strawman already. Meteorites from Earth have hit Mars.

DNA analysis will provide proof as to whether microbes on Mars came from Earth or the other way around.

Note that since Earth’s gravity well is much deeper, an asteroid strike sending ejecta into an escape orbit would have to be much more powerful than a comparable strike on Mars. The energies involved (the ejecta would have to attain at least 11 km./sec to escape) would be more likely to sterilize the microbes.

I would not rule out microbes going Earth to Mars.

No takers for the bet?

1. Source the invented fact.

2. So what?
