NASA: "Building blocks of life" found on Mars.
« on: June 07, 2018, 03:08:17 pm »

Quote
Curiosity's latest data reveal that the watery lake that once filled Mars’s Gale Crater contained complex organic molecules about 3.5 billion years ago. Hints of them are still preserved in sulfur-spiked rocks derived from lake sediments. Sulfur may have helped protect the organics even when the rocks were exposed at the surface to radiation and bleach-like substances called perchlorates.
Not conclusive. But.

Oh, and:
Quote
In addition to ancient carbon, Curiosity has caught whiffs of organics that exist on Mars today. The rover has periodically sniffed Mars’s atmosphere since it landed, and in late 2014, researchers using these data showed that methane—the simplest organic molecule—is present in Mars’s atmosphere.

Methane’s presence on Mars is puzzling, because it survives only a few hundred years at a time, which means that somehow, something on the red planet keeps replenishing it. “It’s a gas in the atmosphere of Mars that really shouldn’t be there," says NASA Jet Propulsion Lab scientist Chris Webster.

I found bricks in the dump. that doesn't prove there used to be a house on that site
OTOH, we don't have any extraterrestrial organisms to look at, so we can only make educated guesses on how similar their chemical structure may or may not be to life on earth

More like finding bricks in the forest, or on en empty lot.

If it's in the dump, you know that there was almost certainly not a house on that site.

"Whichever devotee desires to adore whatever such Deity with faith, in all such votaries I make that particular faith unshakable. Endowed with that faith, a votary performs the worship of that particular deity and obtains the fruits thereof, these being granted by Me alone." - Sri Krishna

Is it necromancy, though? Not like there's been a ton of activity on this part of the forum this summer. T'was one of the more recent threads.

Probably, but not necessarily, so.
I can show you a town at the bottom of a lake, and in the same way that the lake wasn't always there, neither was the dump

Hence why I said 'almost' certainly. Of course, somebody might build a dump on the former site of a house.

I just think that's a poor analogy for Mars... because what makes it a dump?
