It's the blood of Martian sacrifices

Yay,.

Yay,.

That's it?

Personally, I'm curious how these outflows of water have been sustained all this time. Without evaporation to carry the water upward, it has to run out, eventually.

Obviously there's no life on mars but I'm pretty sure there is life somewhere out there, unless the universe is like a really big cylindrical mirror.

Life is everywhere. Our planet/galaxy/universe is probably, in a sense, a living organism. Perhaps a human lifetime is just a fraction of a fraction of a fraction of a second to our planet.
