Looks more and more likely that there was life on Mars.

Wowza! 
Very exciting.

Makes you wonder if Mars had life once. Maybe humans come from Mars??

Maybe we do!

Very interesting stuff

[darkknightkryta]

Does this video say what happened to it?

[Dr. Pezus]

Does this video say what happened to it?

Yeah, it evaporated

[darkknightkryta]

Yeah, it evaporated

I can understand how the water on Venus evaporated, but how does a planet with an average temperature of -55 degrees Celsius evaporate water?

From the article. 
The huge body of water lasted for millions of years. But over time, the Martian atmosphere thinned. The drop in pressure meant more ocean water wafted into space. The planet lost much of its insulation too. No longer warm enough to keep the water liquid, the ocean receded and eventually froze.

I completely forgot pressure affects matter states D: So there's frozen water on Mars still?

Today, only 13% of the ocean remains, locked up the Martian polar caps.

Oh tons of frozen water. The huge north and south ice caps are primarily water ice.

If we came from Mars, then where did life on Mars come from?

Spoiler for nonsenical answer:

Gooch's mom.  ;P

Spoiler for real answer:

I wonder if we'll ever know, perhaps we journeyed further than we could possibly imagine.  Or perhaps it was right here where we all started.

Probably here, life on this planet has died/restarted plenty of times.  Our time will come too when we disappear and some new life regenerates. 

So the ice caps aren't methane eh?

They have a thin covering of co2. South pole co2 freezes during the winter night and sublimates during summer. North pole always has co2, about 8 meters thick.

I created my own word that helps in these questions. Maas=distinct objects that actively work towards producing more copies of themselves, with the ability of mutation/evolution between generation. Life is just a specific type of maas, one with carbon based cells and all that.

Each type of maas has a chance of spontaneous generation out of its environment. As is we can trace all life back to essentially a single colony of prokaryotic cells. If life had high chances of spontaneous generation and would just happen to form on other planets with similar environments, then why wouldn't it have spontaneously formed multiple times on Earth? Earth is billions of years old with tons of water and good materials, and yet there's zero evidence of primitive life just generating itself. I think it's a good sign that the chance of life spontaneously generating are very very very low.

For us to find life on other planets, we'd have to have some connection to each other ala seeding. Either life traveled from us to them, from them to us, or from a 3rd party to both them and us.


For us to find maas on other planets, we'd just have to get lucky.

We've had many mass extinctions, but when did life ever die?

There is life on Mars called anaerobic bacteria
