Mars oceans and the face

You have to remember, too, that Earth's core is 50% bigger than it should be for a planet this size. So, of course the core hasn't cooled yet.

I think the Human-Like-Aliens nuked themselves on Mars and send Marsian life-forms to planet Earth and now, we are going to nuke ourselves on planet Earth and are going to live on planet Mars again...yep, it's a never ending circle.

Humans are stupid, it's just the way it is.

There's no plate tectonics in Mars.

Note! something Guys! you might wann see something moving at 0:53... like someone working from right to left. Work like a human being...

[luxeden]

Yes I have noticed something moving at 0:53 maybe a space ship!

I think Mars was very Earth like before but cooled of to fast for life to form.

[oberonfamily]

kinda weird mars had water 3.5 to 4 billion years ago.... and life started about 3.5 to 4 billion years ago on this planet... just pointing that out...

[Veetina]

Maybe Mars didnt have water as long as 4 billion years ago maybe only a few thousand years ago!

I personally think that Mars used to contain intelligent life until they burned out all of their resources as we are doing right now on Earth.

So if you understand what I am saying then Earth should look somewhat like Mars in the future if I am correct.

Maybe Martians polluted Mars's atmosphere to a pulp; and as a result we have our modern day Mars now.

[luxeden]

Or Mars was bombarded with asteroids that burned out all life forms and all the ressources!

mars one of the most interesting planets in our solar system

[luxeden]

Mars the most interesting because it had water and when we say water we say similar conditions as earth

[orangeblueandlavenda]

maybe mars had life on it before it moved.
