Did lava, not water, form the canyons on Mars?

Of little interest, except it would mean:

The distinction between sedimentary and igneous rocks reaches far beyond geology. If, as the majority of scientists still believe, the valleys and outflow channels once contained significant volumes of water, then they are naturally prime candidates for future missions on the hunt for life. For instance, the European Space Agency’s ExoMars rover, due to touch down in 2019, is considering landing sites around Valles Marineris.

If Leone’s conclusion is accurate, however, and these features are instead mostly volcanogenic, this implies that much less water was present during their formation. If this turns out to be true, their suitability as landing sites could be called into question.

This would not spell doom for the chances of finding life on Mars. If Leone is right, it simply means that less liquid water existed in this particular corner of the planet. It would say little about Mars’ total water inventory.

So, in short, Mars may not have much water and may not be a good candidate for the hunt for life.

YEC sees no big problem with water on mars. However there are other options. a meteor impact could of hit mars time and again and melted ice to bring the canyon carving flows. it could be volcanic explosions mimicking flows as stated here. Anyways there is no life there. The bible says god's sporit overflew the earth and thats how life came. Robert Byers
BA77, are you seriously suggesting that this is the source of Noah’s flood? However, what would happen to the earth’s crust with all of the extra weight of water on top, and much less supporting material beneath the crust to support it?
The source? Don't be silly. The source would have been emptied out when the flood occurred. Rather this is where the floodwaters went after they receded. BTW, are you saying that if the Earth was completely covered in water, we should expect that there would be major tectonic shifts that might cause mountains to rise up and the water to flow away underground? If so, that is very interesting. StephenA

Many Christians believe that the water from Noah's flood is still on the earth, but that the "mountain building" that occurred at one time caused the global flood to recede from about 30% of the earth. This is pretty amazing: http://www.thewire.com/global/2014/03/massive-subterannean-reservoir/359108/

ab the New Living Translation is even more explicit,, Genesis 7:11 - New Living Translation When Noah was 600 years old, on the seventeenth day of the second month, all the underground waters erupted from the earth, and the rain fell in mighty torrents from the sky. ,, take from it what you will, I just find it very interesting that the Bible was correct on there being great reservoirs of water underground centuries before science confirmed it. Of course, atheists, as with everything else, will hold such a discovery of no importance, but from a pure scientific perspective, it is a very interesting confirmation. ,, this discovery sort of reminds me of this gem of a quote from a Bible skeptic who thought it unfair to use the Bible as a guide in archeology since,,,:: ‘he knew immediately that, proceeding in this way (using the Bible as a guide), “she would certainly find that building” https://uncommondesc.wpengine.com/intelligent-design/materialism-vs-science-in-archaeology-and-the-difference-it-makes/ ========== "In Extraordinary ways, modern archaeology has affirmed the historical core of the Old and New testaments - corroborating key points of the stories of Israel's patriarchs, the Exodus, the Davidic monarchy, and the life and times of Jesus." Jeffery Sheler - 'Is The Bible True', U.S. News and World Report, Oct. 25th, 1999, pg.52 ================ Humanpast.net Excerpt: Worldwide, we know that the period of 14,000 to 13,000 years ago, which coincides with the peak of abundant monsoonal rains over India, was marked by violent oceanic flooding - in fact, the first of the three great episodes of global superfloods that dominated the meltdown of the Ice Age. The flooding was fed not merely by rain but by the cataclysmic synchronous collapse of large ice-masses on several different continents and by gigantic inundations of meltwater pouring down river systems into the oceans. (124) What happened, at around 13,000 years ago, was that the long period of uninterrupted warming that the world had just passed through (and that had greatly intensified, according to some studies, between 15,000 years ago and 13,000 years ago) was instantly brought to a halt - all at once, everywhere - by a global cold event known to palaeo climatologists as the 'Younger Dryas' or 'Dryas III'. In many ways mysterious and unexplained, this was an almost unbelievably fast climatic reversion - from conditions that are calculated to have been warmer and wetter than today's 13,000 years ago, to conditions that were colder and drier than those at the Last Glacial Maximum, not much more than a thousand years later. From that moment, around 12,800 years ago, it was as though an enchantment of ice had gripped the earth. In many areas that had been approaching terminal meltdown full glacial conditions were restored with breathtaking rapidity and all the gains that had been made since the LGM were simply stripped away…(124) A great, sudden extinction took place on the planet, perhaps as recently as 11,500 years ago (usually attributed to the end of that last ice age), in which hundreds of mammal and plant species disappeared from the face of the earth, driven into deep caverns and charred muck piles the world over. Modern science, with all its powers and prejudices, has been unable to adequately explain this event. (83) http://humanpast.net/environment/environment11k.htm bornagain77

Related Note; Earth's 'underground oceans' could have three times more water than the surface - June 13, 2014 Excerpt: Scientists have published the first direct evidence of a massive reservoir of water three times the size of Earth’s oceans located hundreds of miles underneath the surface of the planet. The discovery could explain exactly why the Earth is so habitable, with scientists suggesting that this underground store of water – which is trapped in minerals – has acted as a buffer, keeping the Earth’s oceans at roughly the same levels for hundreds of millions of years.,,, between 250 and 410 miles in an area known as the “transition zone”. The H20 is trapped in the molecular structure of minerals within the mantle rock, with this unique form – neither liquid, ice nor vapour – created by the phenomenal pressure and heat underneath the Earth’s surface.,,, Jacobsen and Schmandt's study used data from a network of 2,000 seismometers across America to measure the spread of vibrations from earthquakes. Because these disturbances travel at different speeds through different materials, the scientists were able to infer when the seismic waves hit a patch of ‘soggy’ rock.,,, "We should be grateful for this deep reservoir," he said. "If it wasn't there, it would be on the surface of the Earth, and mountain tops would be the only land poking out." http://www.independent.co.uk/news/science/earths-underground-oceans-could-have-three-times-more-water-than-the-surface-9534266.html Genesis 7:11 In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on the same day all the fountains of the great deep burst open, and the floodgates of the sky were opened. bornagain77

Not to Neil deGrasse Tyson. He has a Teaching Company course on mysteries of nature. The one on life is mainly on OOL and speculates that our life began on Mars and that Mars had water. It spread to Earth via meteor hits sending rocks into space and eventually landing on Earth. He doesn't outright say it but implies the time is too short for it to happen on Earth. It is one of his speculations. jerry
