NASA confirms ancient lakes existed on Mars 2 to 3 billion years ago
Billions of years ago, there were lakes shimmering on Mars..
That is the conclusion from the team behind NASA's Mars Science Laboratory/Curiosity, who used data from the Curiosity rover to determine that water helped deposit sediment into Gale Crater. Three years ago, the rover landed at the crater and it has been exploring the area ever since.
"Observations from the rover suggest that a series of long-lived streams and lakes existed at some point between about 3.8 to 3.3 billion years ago, delivering sediment that slowly built up the lower layers of Mount Sharp," said Ashwin Vasavada, Mars Science Laboratory project scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif, and co-author of the new Science article to be published Friday, in a press release.

I don't doubt Mars once had lakes and streams. There is evidence from the flattened surface of once side of Mars' globe that it suffered a cataclysmic collision with another heavenly body sometime in its past. That would certainly explain its loss of atmosphere, and the planet-wide drought that belies its past.
But being a YEC'er, I seriously doubt that was more than ten thousand years ago. But that's just me, I guess. Wonder what believing scientists think?
