Just imagine the accomplishments in space humanity could do in space if our kind wasn’t fighting other countries all the time.

That little rover was not native to Mars, thus making it an alien craft.

[astyanax]

Wow, this episode was much more scientific than most of them

[norikumo]

"Plot twist we are the aliens" !)

[kaitlinsmackenzie]

6 years on mars and the camera lense is still so clean😕😂 ? I wonder who takes care of the little robot?

[gregoryvelikovsky]

Seems as though Mars is trying to rebuild its atmosphere literally from the ground up

[tomjonese]

If our atmosphere became compromised, I think we'd be forced to move underground, like martians did maybe thousands of life cycles ago.

[zadianvwhgaming]

There’s alien megacities underground on Mars, duh

[parmeshwaranacharya]

Seems like Mars is getting prepared for complex life

[joshglover]

What if the survivors of the cataclysm still live below the surface, safe from the harmful radiation and inadequate oxygen levels on the surface?

[crealix]

Mars for me is just a mirror of this place if people will not taking care of it..

[humanofearth]

I’ve had just the worst methane all day today.

[earthychild]

Look up. There are a lot of aliens in the sky this days. A lot of spaceship. What's going on

[tonyloche]

So good, they didn’t even have to have an ancient astronaut theorist get carried away with a hypothesis at the end. 😂

[watcharatphairatphiboon]

I’m so happy I’m living in a real life science fiction movie.

[FormulatedButterCoping]

If life is ever found on Mars, it will be interesting to learn how it survives with such very low oxygen levels.

[ClashGardener]

*Well if we're up there, it's a given.*

[joshglover]

I hope to set foot on this beautiful planet one day! 😀

There is truth in everything we watch because at one time man was there until a supernova set us back to the stone ages .
