Reply to comment by AlexandersWonder in NASA discovery reveals there may have been life on Mars by Genevieves_bitch

In August 1996, a group of scientists announced that they had found evidence of ancient life on Mars. This evidence included bacteria-shaped objects and organic chemical molecules in the martian meteorite ALH 84001, which was collected in Antarctica.

I don't care about a single possible cell. Show me a group of possible cell and show me that they were eating something in the rock and show me the poop.

Life on other planets doesn’t need cells.

Hwat are you talking about. Cells=life. Chemical soup is not life unless it has a cell wall of some sort.

Our definitions of life match what we've seen, not what it must be.

I'd think that if we saw evidence of some sort of amorphous autonomous chemical soup on another planet moving around and making decisions, we might have to start reconsidering some things.

Self replicating Campbell’s soup, it would be endless soup.

I always thought about how when we say “nothing can live in _______” that we could only say that because we can’t imagine what could live in places we see as uninhabitable for us.

I can show you my poop. I have a big one in the oven almost ready.

Reddit has proven that something can poop, yet still have no life.

That's not believed to be good evidence of past life on Mars because the objects are tiny, much smaller than any known terrestrial bacteria. Researchers were also able to produce similar shapes using non-biological methods.

It's still possible these are some kind of life much smaller than earth life, but it's thought unlikely.

You think todays findings are bullet proof?

Just tempting expectations, as ALH 84001 is often overhyped as solid evidence of past life on Mars.
